A recovery code is a "backup authentication code" used when you are unable to receive an authentication code via your smartphone or other device while using two-factor authentication.
[Main Points]
- When you set up two-factor authentication, 10 recovery codes will be issued.
- Even if you cannot obtain the code via an authentication app or SMS, you can still log in using a recovery code.
- Recovery codes are extremely important, so please be sure to store them in a safe place.
