A guide to fix common issues with two-factor authentication (2FA) problems.

If you've lost or broken your phone:

• Use your saved backup codes to access your account
• Contact support if you don't have backup codes

For authentication app users with a new phone:

1. Disable 2FA in account settings
2. Click "Set up" next to Authentication App
3. Scan the QR code on your new device

For text message verification with a new number:

1. Disable 2FA in account settings
2. Click "Set up" next to Text Message
3. Enter your new phone number

If you're not receiving text messages:

• Verify the phone number shown on the login screen
• Check network connectivity
• Click "Use another method" to resend the code

Common error solutions:

• Incorrect/expired codes: Wait for new code and retry
• Authentication app issues: Ensure phone time is set to automatic
• Text message codes: Valid for 5 minutes only
• Invalid phone format: Enter number without country code (e.g., 555-555-5555)

Additional troubleshooting:

• Can't install authentication app: Use text message or security key instead
• Country not listed: Use authentication app or security key
• Security key issues: Follow browser/device manufacturer instructions
• Mobile app login problems: Update to the latest version

Contact support if:

• You can't access your backup codes
• Setup issues persist
• Login attempts fail after trying all solutions

Note: Always save your backup codes securely during initial setup for emergency access.
