In addition to securely storing your two-factor authentication (2FA) recovery codes, we strongly recommend configuring two or more authentication methods to avoid losing access to your account. For more information, see "Configuring two-factor authentication."
Downloading your two-factor authentication recovery codes
When you configure two-factor authentication, you'll download and save your 2FA recovery codes. If you lose access to your phone, you can authenticate to GitHub using your recovery codes. You can also download your recovery codes at any point after enabling two-factor authentication.
To keep your account secure, don't share or distribute your recovery codes. We recommend saving them with a secure password manager.
If you generate new recovery codes or disable and re-enable 2FA, the recovery codes in your security settings automatically update. Reconfiguring your 2FA settings without disabling 2FA will not change your recovery codes.

Configuring backups for your time-based one-time password (TOTP) app
Most TOTP apps support backups. If you lose access to your authentication device, you can use your TOTP app backup to access your authentication method and account credentials on a different authentication device, ensuring continued access to your 2FA-enabled account.
The process of configuring backups is different for each TOTP app. For some examples from popular TOTP apps, see the following documentation:
