Troubleshoot Two-Factor Authentication
Solve common issues with two-factor authentication codes, apps, and recovery options.
Common Problems & Solutions
1. "Invalid Code" Error
Check if your authenticator app is synchronized. If using a hardware key, ensure it's fully charged and properly connected.
Fix: Re-synchronize your authenticator app or temporarily disable and re-enable 2FA in your account settings.
2. App Not Responding
Restart the authenticator app or device. Ensure the app has permission to access your device's clock.
Fix: Reinstall the authenticator app while ensuring correct QR code scanning during setup.
3. Lost Access Device
Use your backup recovery codes or enable 2FA using a new device with the same account.
Fix: Access 2FA Setup to manage devices directly in your account settings.
Advanced Troubleshooting
Time Sync Issues
Authenticator apps depend on accurate device time. If your time is out of sync by more than 1 minute, codes will fail.
Manual Code Re-entry
If the QR code scan fails, manually enter the 2FA key during setup, found in your account's 2FA settings.
Recovery Options
Backup Codes
Use one-time backup codes if you can't access your 2FA device. These codes can be downloaded during setup.
