Dart Reference v2.0

Auth MFA

This section contains methods commonly used for Multi-Factor Authentication (MFA) and are invoked behind the supabase.auth.mfa namespace.

Currently, we only support time-based one-time password (TOTP) as the 2nd factor. We don't support recovery codes but we allow users to enroll more than 1 TOTP factor, with an upper limit of 10.

Having a 2nd TOTP factor for recovery means the user doesn't have to store their recovery codes. It also reduces the attack surface since the recovery factor is usually time-limited and not a single static code.
