Account Access FAQ

Common questions about logging in, syncing, recovering, and accessing your ZelCore account across devices.

Account Types and Login​

What's the difference between a legacy account and a seed phrase account?​

Answer:

ZelCore has two account types with different login methods:

Legacy Account (Old System):

  • Uses username and password to log in
  • Created before 2022
  • Centralized account system
  • Being phased out
  • Still works but migration recommended

Seed Phrase Account (Modern System):

  • Uses 12 or 24-word seed phrase
  • Industry-standard BIP44 protocol
  • No username/password
  • Fully decentralized
  • Recommended for all users

How to tell which you have:

  • If you log in with username/password → Legacy account
  • If you have a 12/24-word seed phrase → Modern account

Should I migrate from legacy to seed phrase?​

Answer:

Yes, migration is strongly recommended. Here's why:

Benefits of migrating:

  • Better security with BIP44 standard
  • Full ownership without reliance on ZelCore servers
  • Works with other BIP44-compatible wallets
  • Access to latest features and updates
  • Future-proof as legacy accounts are being deprecated

When to migrate:

  • As soon as you have 30-60 minutes of free time
  • When you can carefully follow the migration process
  • After updating ZelCore to the latest version

Legacy account status:

  • Still functional now
  • No immediate deadline
  • But will be phased out eventually
  • Earlier migration is better

How do I know if I have a seed phrase?​

Answer:

If you have a modern account:

  • You wrote down 12 or 24 words when creating your wallet
  • These words are in a specific order
  • You don't use a username/password to log in

If you're unsure:

  1. Check your records:

    • Look for a written recovery phrase
    • 12 or 24 common English words
    • Numbered in sequence

  2. Check in ZelCore (if logged in):

    • Go to Settings → Security → Show Seed Phrase
    • Requires authentication
    • If option doesn't exist, you may have legacy account

  3. Based on login method:

    • If you enter username/password → No seed phrase (legacy account)
    • If you enter PIN/biometric per device → You have a seed phrase

If you have a legacy account without seed phrase:

Sync vs Register - New Device Setup​

What's the difference between "Sync" and "Register" on a new device?​

Answer:

This is one of the most common sources of confusion. Understanding the difference is critical:

"Sync" or "Import Wallet":

  • Use when: You already have a ZelCore account
  • What it does: Gives you access to your EXISTING wallet
  • You need: Your seed phrase or legacy credentials
  • Result: You see your existing funds and transaction history

"Register" or "Create New Wallet":

  • Use when: You're a brand new ZelCore user
  • What it does: Creates a COMPLETELY NEW wallet
  • You need: Nothing - generates new seed phrase
  • Result: Empty wallet with new addresses

The confusion:

  • "Sync" does NOT sync automatically
  • You must provide your credentials
  • Many users choose "Register" by mistake
  • This creates a second empty wallet

Think of it like email:

  • Sync = Log into existing email account
  • Register = Create brand new email account

Related:

I chose "Register" instead of "Sync" and my balance is zero. What do I do?​

Answer:

Don't panic - your funds are safe! This is a very common mistake. You created a new empty wallet instead of accessing your existing one.

Quick fix:

  1. Close ZelCore completely

    • Force quit the app
    • Don't just minimize it

  2. Reopen ZelCore

    • Look for "Account Switcher" or "Manage Accounts"
    • Or log out and return to welcome screen

  3. Choose "Sync" or "Import Wallet" this time

    • NOT "Register" or "Create New"
    • Select "Import from Seed Phrase" or "Legacy Login"

  4. Enter your credentials:

    • For seed phrase accounts: Enter your 12/24 words
    • For legacy accounts: Enter username and password

  5. Your funds will appear

    • Original wallet is unchanged
    • Funds were always on the blockchain
    • You just created a second empty wallet by accident

Optional:

  • You can keep both wallets
  • Use account switcher to manage multiple accounts
  • Or ignore the empty wallet

What does "Sync" actually sync? Is it automatic?​

Answer:

"Sync" is a misleading name - it's not automatic synchronization. Here's what it really means:

What "Sync" really does:

  • It's actually "Import existing wallet to this device"
  • Requires you to provide seed phrase or login credentials
  • Downloads your wallet configuration to the new device
  • Connects to blockchain nodes to fetch your balances

What "Sync" does NOT do:

  • Does NOT automatically sync across devices
  • Does NOT remember your credentials from other devices
  • Does NOT transfer data from another device
  • Does NOT backup your wallet automatically

Why the confusion:

  • Many apps use "sync" to mean automatic cloud sync
  • ZelCore's "sync" is really "import" or "restore"
  • The naming causes widespread confusion

What actually syncs automatically:

  • Transaction history (from blockchain)
  • Balance updates (via Smartify)
  • Asset lists (after initial sync)

What requires manual action:

  • Initial setup on new device (must enter seed phrase)
  • Account recovery (must have seed phrase)
  • Cross-device access (must import on each device)

Accessing Account on New Device​

How do I access my ZelCore account on a new phone/computer?​

Answer:

Follow these steps carefully to access your existing account on a new device:

Step 1: Install ZelCore

  • Download from zelcore.io (desktop) or app store (mobile)
  • Install and open the app

Step 2: Choose the CORRECT option

  • Select "Sync," "Import Wallet," or "Restore from Seed Phrase"
  • DO NOT select "Register" or "Create New Wallet"

Step 3: Choose account type

For seed phrase accounts:

  1. Select "Import from Seed Phrase" or similar
  2. Enter all 12 or 24 words in exact order
  3. Verify spelling and order
  4. Continue

For legacy accounts:

  1. Look for "Legacy Account" or "Username/Password Login"
  2. May be under "Advanced" or "More Options"
  3. Enter your username and password
  4. Log in

Step 4: Set up device authentication

  • Create PIN, password, or use biometric
  • This is DEVICE-SPECIFIC
  • Different from your seed phrase

Step 5: Wait for sync

  • App will connect to blockchain nodes
  • May take 1-3 minutes
  • Run Smartify if balances don't appear immediately

Step 6: Verify

  • Check that all assets appear
  • Verify balances match expectations
  • Test sending/receiving if needed

Common mistakes to avoid:

  • ❌ Choosing "Create New" instead of "Import"
  • ❌ Typing seed phrase with errors
  • ❌ Using wrong word order
  • ❌ Confusing device PIN with seed phrase

Do I need to sync my account every time I switch devices?​

Answer:

You don't "sync" between devices - you import your wallet to each device independently.

How it works:

Initial setup on each device:

  • Import wallet once per device using seed phrase
  • Set up device-specific authentication
  • After initial import, that device stays logged in

Subsequent use:

  • Open ZelCore and authenticate (PIN/biometric)
  • No need to re-enter seed phrase each time
  • Balances update automatically via blockchain connection

Switching between devices:

  • Each device maintains its own logged-in session
  • No manual syncing needed
  • Transactions appear on all devices (from blockchain)
  • Settings may vary per device

When you need your seed phrase again:

  • Setting up a brand new device
  • Recovering after losing a device
  • Reinstalling ZelCore
  • Factory reset of device

Data that stays in sync automatically:

  • Balances (from blockchain)
  • Transactions (from blockchain)
  • Assets (after initial setup)

Data that doesn't sync:

  • Device-specific settings
  • Local PIN/password
  • Custom labels or notes (device-specific)

I lost my phone. How do I recover my account?​

Answer:

If you have your seed phrase, recovery is straightforward. If not, recovery may be difficult or impossible.

If you HAVE your seed phrase:

Immediate steps:

  1. Get a new device (phone/computer)
  2. Install ZelCore
  3. Choose "Import Wallet" or "Sync"
  4. Enter your 12 or 24-word seed phrase
  5. Your wallet will be fully restored

Your funds are safe:

  • Cryptocurrency is on the blockchain, not the device
  • Seed phrase gives access to your funds
  • All balances will appear after import

Additional security steps:

  1. Change any passwords if phone was stolen
  2. Enable D2FA on new device
  3. Review security settings
  4. Consider if anyone accessed your seed phrase

If you DON'T HAVE your seed phrase:

For seed phrase accounts:

  • Recovery is impossible without the seed phrase
  • No backdoor or recovery method exists
  • Funds are permanently inaccessible
  • This is why seed phrase backup is critical

For legacy accounts:

  • Password recovery may be available
  • Contact ZelCore support
  • May require identity verification
  • Not guaranteed but possible

Prevention for future:

  • Write down seed phrase immediately
  • Store in multiple secure locations
  • Test recovery on different device
  • Keep backup device with ZelCore installed

D2FA and Security​

What is D2FA and how is it different from regular 2FA?​

Answer:

D2FA stands for "Decentralized Two-Factor Authentication" - ZelCore's enhanced security feature.

How D2FA works:

  • Uses distributed blockchain network for verification
  • No centralized server stores your authentication data
  • Requires your D2FA PIN for high-value transactions
  • More secure than traditional SMS or app-based 2FA

Key differences from regular 2FA:

Traditional 2FA:

  • Centralized servers (Google, SMS)
  • Vulnerable to server hacks
  • Can be intercepted (SMS)
  • Requires internet connection to central server

ZelCore D2FA:

  • Decentralized blockchain-based
  • No central point of failure
  • Cannot be intercepted
  • Uses distributed node network

When D2FA is required:

  • Large transaction amounts
  • Changing security settings
  • Withdrawing funds
  • Can be configured in settings

Setting up D2FA:

  1. Go to Settings → Security
  2. Enable D2FA
  3. Create D2FA PIN (6-8 digits)
  4. Confirm PIN
  5. Backup PIN securely

Related:

I forgot my D2FA PIN. How do I reset it?​

Answer:

You can reset your D2FA PIN using your seed phrase, but the process requires careful steps.

For seed phrase accounts:

  1. Have your seed phrase ready:

    • All 12 or 24 words
    • In correct order
    • Spelled correctly

  2. Reset D2FA:

    • Go to Settings → Security → D2FA
    • Look for "Reset D2FA" or "Forgot PIN"
    • May need to re-import wallet

  3. Re-import method (if needed):

    • Log out of ZelCore
    • Choose "Import Wallet"
    • Enter your seed phrase
    • Set up new D2FA PIN during import

  4. Set new PIN:

    • Choose a memorable but secure PIN
    • Write it down in secure location
    • Don't use same PIN as device authentication

For legacy accounts:

  • Contact ZelCore support
  • May require identity verification
  • Process may take 24-48 hours

Prevention:

  • Write down D2FA PIN when you create it
  • Store separately from seed phrase
  • Don't use birthdates or obvious numbers
  • Test D2FA after setting up

Security note:

  • Anyone with your seed phrase can reset D2FA
  • Keep seed phrase extremely secure
  • D2FA adds security but seed phrase is ultimate key

D2FA keeps failing when I try to approve transactions. What's wrong?​

Answer:

D2FA failures usually relate to connectivity, incorrect PIN, or sync issues.

Common causes and solutions:

1. Incorrect PIN:

  • Verify you're entering the correct D2FA PIN
  • D2FA PIN is different from device PIN
  • Check for typos or caps lock
  • Try resetting PIN if you're unsure

2. Internet connection issues:

  • D2FA requires internet to communicate with blockchain nodes
  • Check your connection is stable
  • Try switching between WiFi and mobile data
  • Disable VPN temporarily

3. App needs update:

  • Update ZelCore to latest version
  • Restart app after updating
  • Try D2FA again

4. D2FA sync issues:

  • Go to Settings → Smartify
  • Run Smartify to refresh connections
  • Try D2FA transaction again

5. Blockchain node problems:

  • Specific blockchain nodes may be down
  • Try changing backend server (Settings → Backend)
  • Wait a few minutes and retry

6. Time sync issues (desktop):

  • Computer clock must be accurate
  • Set to automatic time sync
  • Correct timezone
  • D2FA uses timestamps for verification

Step-by-step troubleshooting:

  1. Verify internet connection
  2. Update ZelCore
  3. Run Smartify
  4. Verify D2FA PIN is correct
  5. Check device time is accurate
  6. Try different backend server
  7. Restart ZelCore
  8. Try transaction again

If still failing:

  • Transaction amount may be below D2FA threshold
  • Disable and re-enable D2FA
  • Contact support with error messages

I entered my seed phrase but ZelCore says it's invalid. What's wrong?​

Answer:

Seed phrase errors usually involve typos, wrong words, incorrect order, or wrong word count.

Common issues and solutions:

1. Word order is wrong:

  • Words must be in EXACT order
  • Word #1 must be first, word #12 must be last
  • Write numbers next to each word
  • Verify order matches original backup

2. Spelling errors:

  • Check each word carefully
  • BIP39 word list has specific valid words
  • Common confusions: "world" vs "word", "through" vs "though"
  • All lowercase usually
  • No punctuation

3. Wrong number of words:

  • Should be exactly 12 or 24 words
  • Not 13, not 11
  • Count carefully
  • Verify against backup

4. Extra spaces:

  • Only single space between words
  • No spaces at beginning or end
  • No double spaces
  • Trim all whitespace

5. Wrong word list language:

  • Most seed phrases are English
  • Some wallets support other languages
  • Try English first
  • Check what language you used originally

6. Autocorrect interference:

  • Disable autocorrect when entering
  • Type manually, don't use voice
  • Verify each word individually
  • Use on-screen keyboard if available

Verification tips:

Check against BIP39 word list:

  • Official word list: github.com/bitcoin/bips/blob/master/bip-0039/english.txt
  • All words must be from this list
  • Only 2048 valid words
  • If word isn't on list, it's misspelled

Common misspellings:

  • "wolf" vs "women"
  • "abandon" vs "ability"
  • "all" vs "always"
  • "example" vs "expand"

Double-check your backup:

  • Re-read original written phrase
  • Look for smudged or unclear words
  • Compare what you wrote to what you're typing
  • Check if you accidentally skipped a word

Try import on different device:

  • Sometimes app-specific issues
  • Try desktop vs mobile
  • Try different version of ZelCore
  • Rules out device-specific problems

If seed phrase is definitely correct but still failing:

  1. Try different import method:

    • Some wallets have "advanced import"
    • Try selecting BIP44 specifically
    • May need to specify derivation path

  2. Verify seed phrase elsewhere:

    • Try importing in another BIP44 wallet (MetaMask, Trust Wallet)
    • If works there, issue is ZelCore-specific
    • If fails everywhere, seed phrase is wrong

  3. Check for variant seed phrases:

    • Some people write down multiple seed phrases
    • Verify you're using correct one
    • Check all backups you have

Last resort - if you're logged in elsewhere:

  • Access account on device where still logged in
  • Go to Settings → Security → Show Seed Phrase
  • Write down correct phrase
  • Compare to what you've been trying

Prevention:

  • Write clearly when backing up
  • Use printed templates
  • Create multiple backups
  • Verify seed phrase immediately after creating
  • Test recovery before storing large amounts

I accidentally created a new account instead of accessing my old one. Can I switch?​

Answer:

Yes, you can easily switch between accounts. Creating an extra account doesn't affect your original one.

How to access your original account:

Method 1: Account Switcher (Recommended)

  1. Look for account menu:

    • Top right corner or settings
    • "Accounts," "Profiles," or "Switch Account"
    • May be a profile icon

  2. Add your original account:

    • Select "Add Account" or "Import Account"
    • Choose "Import from Seed Phrase" or "Legacy Login"
    • Enter your original credentials

  3. Switch between accounts:

    • Use account switcher menu
    • Select which account to view
    • Both accounts remain accessible

Method 2: Log Out and Log In

  1. Log out of current account:

    • Settings → Log Out
    • Or Account → Sign Out

  2. Return to welcome screen:

    • Choose "Sync" or "Import"
    • Enter your original seed phrase or credentials

  3. Access original account:

    • Your funds will appear
    • Original account is unchanged

Method 3: Delete and Reinstall (Not recommended)

  1. Delete ZelCore app
  2. Reinstall ZelCore
  3. Choose "Import" or "Sync"
  4. Enter original credentials

Your original account is safe:

  • Creating new account doesn't affect old one
  • Funds remain on blockchain
  • Both accounts can coexist
  • You can use both or ignore the new one

Going forward:

To use both accounts:

  • Keep both imported
  • Use account switcher to change between them
  • Useful for separating funds

To use only original:

  • Just ignore the new empty account
  • Or remove it from account list if option exists
  • Focus on your original account

Prevention next time:

  • Remember: "Sync/Import" = existing account
  • "Register/Create" = new account
  • Read options carefully before selecting

Can I have multiple ZelCore accounts?​

Answer:

Yes, ZelCore supports multiple accounts, and you can switch between them easily.

How to use multiple accounts:

Method 1: Multiple seed phrases

  • Create or import multiple seed phrase accounts
  • Each has its own 12/24-word phrase
  • Use account switcher to change between them
  • Each account is completely independent

Method 2: Multiple devices

  • Use different accounts on different devices
  • Device A: Account 1
  • Device B: Account 2
  • No need to switch

Method 3: Combination

  • Import multiple accounts on one device
  • Also keep separate accounts on different devices
  • Maximum flexibility

Common use cases:

Personal vs Business:

  • Separate account for business transactions
  • Different account for personal crypto
  • Clean separation for tax purposes

Security tiers:

  • Hot wallet for daily use (small amounts)
  • Cold wallet for storage (large amounts)
  • Different seed phrases for each

Testing vs Production:

  • Test account for experimenting
  • Main account for actual funds
  • Learn without risking main funds

Family accounts:

  • Separate accounts for family members
  • Each person has their own seed phrase
  • Can all be on same device (with different profiles)

Managing multiple accounts:

Keep organized:

  • Label accounts clearly ("Main," "Trading," "Savings")
  • Use different device PINs if helpful
  • Document which seed phrase goes with which account

Security considerations:

  • Store each seed phrase separately
  • Label seed phrase backups clearly
  • Don't mix up seed phrases
  • Each account is independent security-wise

Switching between accounts:

  1. Open account switcher (usually in settings or top menu)
  2. Select account to view
  3. All accounts stay logged in
  4. Quick switching without re-entering seed phrase

Limitations:

  • Each account requires separate import on each device
  • Settings don't sync between accounts
  • Transaction history is per account
  • Need to track multiple seed phrases

Best Practices​

How should I securely store my seed phrase?​

Answer:

Your seed phrase is the key to your funds. Proper storage is critical.

Best practices:

Physical storage:

  • ✅ Write on paper with permanent pen
  • ✅ Use metal backup plates for durability
  • ✅ Store in fireproof/waterproof safe
  • ✅ Create multiple copies in different secure locations
  • ✅ Number each word clearly (1-12 or 1-24)

What NOT to do:

  • ❌ Never store digitally (photos, files, cloud)
  • ❌ Never share with anyone (including "support")
  • ❌ Never enter on websites (except wallet import)
  • ❌ Don't store with other important documents that could be stolen
  • ❌ Don't store in obviously labeled containers ("Bitcoin seed")

Multiple copies strategy:

  • Copy 1: Primary safe at home
  • Copy 2: Safety deposit box at bank
  • Copy 3: With trusted family member in sealed envelope
  • Different physical locations protect against disaster

Advanced options:

Metal backup plates:

  • Fire-resistant
  • Water-resistant
  • Long-lasting
  • Available from crypto hardware vendors

Split storage (advanced):

  • Split seed phrase into parts
  • Store parts in different locations
  • Requires combining to access funds
  • More complex but more secure

Estate planning:

  • Instructions for heirs
  • Sealed envelope with lawyer
  • Safe deposit box with trusted executor
  • Document how to access funds

What to include with seed phrase:

  • Date created
  • "ZelCore seed phrase" label
  • Recovery instructions for family
  • DO NOT include account balances or values

Testing your backup:

  • After creating wallet, import on different device
  • Verify seed phrase works
  • Then remove from test device
  • Proves your backup is correct

Security reminders:

  • Anyone with seed phrase controls your funds
  • No recovery method if lost

Should I use the same seed phrase on multiple devices?​

Answer:

Yes, that's how it's designed to work. Your seed phrase gives access to your wallet on any device.

How it works:

One seed phrase, many devices:

  • Import same seed phrase on phone, tablet, computer
  • All devices access same wallet
  • Same addresses, same balances
  • Transactions appear on all devices

Device-specific settings:

  • Each device has its own PIN/password
  • Local settings don't sync
  • Can have different security on each device
  • One device compromised doesn't automatically compromise others

Security considerations:

Benefits of multiple devices:

  • Backup if one device fails
  • Convenience of access anywhere
  • No single point of failure

Risks:

  • Each device is a potential vulnerability
  • If one device compromised, wallet at risk
  • More devices = larger attack surface
  • Lost/stolen device could expose funds

Best practices:

Secure each device:

  • Strong device PIN/password
  • Biometric authentication if available
  • Device encryption enabled
  • Keep devices updated

Limit active devices:

  • Only import on devices you actively use
  • Don't import on public/shared computers
  • Remove wallet from devices you no longer use

Consider device trust levels:

High security devices (large amounts):

  • Desktop at home
  • Personal phone
  • Well-secured devices
  • Where you keep most funds

Convenience devices (small amounts):

  • Mobile for daily use
  • Keep minimal balances
  • For routine transactions

Never import on:

  • ❌ Public computers
  • ❌ Work computers you don't own
  • ❌ Shared family devices
  • ❌ Devices you don't fully control

If device is lost/stolen:

Immediate actions:

  1. Transfer funds to new wallet:

    • Create new seed phrase on different device
    • Transfer all crypto to new wallet
    • Old wallet is now compromised

  2. Don't reuse old seed phrase:

    • Generate completely new seed phrase
    • Old phrase may be compromised
    • Start fresh for security

Recommended setup:

Most users:

  • Primary device (phone or desktop)
  • Backup device (kept secure at home)
  • Both import same seed phrase
  • Daily use on primary only

High-security users:

  • Single device for large amounts
  • Different wallet for daily use
  • Limit exposure of main holdings

What should I do before getting a new phone or computer?​

Answer:

Critical: Verify you have your seed phrase BEFORE replacing your device.

Essential pre-replacement checklist:

1. Verify seed phrase access:

  • Open ZelCore on current device
  • Go to Settings → Security → Show Seed Phrase
  • Verify it matches your written backup
  • If no backup, write it down NOW
  • Test the phrase by importing on different device (optional but recommended)

2. Document your setup:

  • List all assets you have
  • Note any custom tokens
  • Screenshot settings (not including sensitive info)
  • Note any special configurations

3. Test recovery (recommended):

  • Install ZelCore on a different device
  • Import using seed phrase
  • Verify all assets appear
  • Then remove from test device
  • Proves your backup works

4. Secure additional backups:

  • Create second seed phrase copy
  • Store in different location
  • Update storage if needed

After getting new device:

Setup process:

  1. Install ZelCore on new device
  2. Choose "Sync" or "Import Wallet"
  3. Enter your seed phrase
  4. Set up device authentication
  5. Run Smartify
  6. Verify all assets appear

Old device handling:

Before wiping old device:

  • Verify new device works completely
  • Check all balances on new device
  • Test sending/receiving on new device
  • Keep old device functional for a week (backup)

When ready to wipe:

  • Log out of ZelCore on old device
  • Uninstall ZelCore
  • Factory reset device
  • Seed phrase remains safe (on paper)

What NOT to do:

  • ❌ Don't wipe old device before setting up new one
  • ❌ Don't assume seed phrase is backed up - verify
  • ❌ Don't skip testing recovery
  • ❌ Don't rush the process

Emergency scenarios:

Old device died/broken:

  • Install ZelCore on new device
  • Import using seed phrase
  • Your funds are safe on blockchain
  • Seed phrase is all you need

Lost/stolen device:

  • Get new device
  • Import with seed phrase
  • Consider transferring to new wallet (new seed phrase)
  • Old wallet may be compromised

Device upgrade timeline:

Week before:

  • Verify seed phrase backup
  • Test recovery if possible
  • Document setup

Day of upgrade:

  • Set up ZelCore on new device
  • Verify everything works
  • Keep old device active

Week after:

  • Confirm new device works perfectly
  • Then wipe old device
