FAQ

Q: How does 2FAS improve security compared to SMS-based 2FA?

A: Unlike SMS-based 2FA, which can be intercepted via SIM-swapping attacks, 2FAS generates time-based (TOTP) or counter-based (HOTP) codes directly on your device. These codes work offline and cannot be stolen through phone number hijacking.

Q: Can I sync my 2FA tokens across multiple devices?

A: Yes! 2FAS allows secure cross-device synchronization, so you can access your 2FA tokens on multiple mobile devices without losing access if one is lost or damaged.

Q: What happens if I lose my phone? Can I recover my 2FA accounts?

A: Absolutely. 2FAS provides backup and recovery options to restore your tokens. You can securely export and import your codes to a new device, ensuring you never get locked out.
