Using a two-factor authentication recovery code

Use one of your recovery codes to automatically regain entry into your account. You may have saved your recovery codes to a password manager or your computer's downloads folder. The default filename for recovery codes is github-recovery-codes.txt. For more information about recovery codes, see "Configuring two-factor authentication recovery methods."

1. Type your username and password to prompt authentication.

   Warning: If you protect your personal account with two-factor authentication but do not know your password, you will need to start a two-factor authentication recovery request. For more information, see "Request help with two-factor authentication."

2. Under "Having problems?", click Use a recovery code or request a reset.

3. Type one of your recovery codes, then click Verify.

Authenticating with a passkey

If you have added a passkey to your account, you can use your passkey to automatically regain access to your account. Passkeys satisfy both password and 2FA requirements, so you don't need to know your password in order to recover your account. For more information, see "About passkeys."

Authenticating with a security key

If you configured two-factor authentication using a security key, you can use your security key as a secondary authentication method to automatically regain access to your account. For more information, see "Configuring two-factor authentication."

Authenticating with a fallback number

If you lose access to your preferred TOTP app or phone number, you can provide a two-factor authentication code sent to your fallback number to automatically regain access to your account.

Authenticating with a verified device, SSH token, or personal access token

If you know your password for GitHub.com but don't have the two-factor authentication credentials or your two-factor authentication recovery codes, you can have a one-time password sent to your verified email address to begin the verification process and regain access to your account.

You can use your two-factor authentication credentials or two-factor authentication recovery codes to regain access to your account anytime during the 3-5 day waiting period.

1. Type your username and password to prompt authentication.

   Warning: If you protect your personal account with two-factor authentication but do not know your password, you will need to start a two-factor authentication recovery request. For more information, see "Request help with two-factor authentication."

2. Under "Having problems?", click Use a recovery code or request a reset.

   

3. Under "Locked out?", click Recover your account or unlink an email address.

4. Click I understand, get started to request a reset of your authentication settings.

5. Click Send one-time password to send a one-time password to all eligible addresses associated with your account. Only verified emails are eligible for account recovery. If you've restricted password resets to your primary and/or backup addresses, these addresses are the only addresses eligible for account recovery.

6. Under "One-time password", type the temporary password from the recovery email GitHub sent, then click Verify email address.

7. Choose a recovery verification factor.

Requesting help with two-factor authentication

If you have forgotten your password and you've lost access to your two-factor authentication credentials, you can start account recovery to regain access to your account. You'll need to verify your identity using a recovery authentication factor, such as an SSH key or previously verified device. If no recovery methods are available, you can choose to unlink your email address from your account.

1. Click Forgot password?.
2. Enter a primary or backup email address associated with your account on GitHub.com, then click Send password reset email.
3. Check your email for a link to reset your password. You must click on this link within three hours of receiving the email. If you don't see an email from us, make sure to check your spam folder.
