Two-Factor Authentication (2FA) is the definitive barrier protecting your exchange balance. Yet, many fear losing account access if their phone gets lost. We show you how to configure 2FA safely and recover accounts in emergencies.
Why Rely on Authenticator Apps?
SMS-based 2FA codes are vulnerable to SIM-swapping. You must utilize dedicated software authenticators (like Google Authenticator or Twilio Authy) for robust security.
The Backup Rule to Prevent Lockouts
When initializing Google Authenticator, a backup setup key (or recovery QR code) is displayed. Write this key on paper and store it offline. This recovery key allows you to restore your 2FA codes instantly on a replacement phone.
What to Do If Your Phone is Lost with No Backups
- Contact Exchange Support Immediately: Request an immediate temporary account freeze.
- Submit Re-Verification Files: Complete identity checks to request a manual 2FA reset from the compliance team.
