Recovering your account if you lose your 2FA credentials

In this article

If you lose access to your two-factor authentication credentials, you can use your recovery codes, or another recovery option, to regain access to your account.

Warnings:

  • 2 要素認証の認証情報をなくしたり、アカウントのリカバリ方法が利用できなくなったりした場合、セキュリティ上の配慮から、GitHub サポートでは 2 要素認証が有効になっているアカウントへのアクセスはリストアできないことがあります。

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: 2 要素認証で個人アカウントを保護してもパスワードがわからない場合は、次の手順に従ってアカウントを回復することはできません。 GitHub は、アカウントに関連付けられている確認済みのアドレスにパスワード リセットの電子メールを送信できます。 詳細については、「GitHub のアクセス資格情報の更新」を参照してください。

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

Authenticating with a fallback number

If you lose access to your primary 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 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 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.

Note: For security reasons, regaining access to your account by authenticating with a one-time password can take up to three business days. GitHub will not review additional requests submitted during this time.

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.

  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.

    • If you've used your current device to log into this account before and would like to use the device for verification, click Verify with this device.
    • If you've previously set up an SSH key on this account and would like to use the SSH key for verification, click SSH key.
    • If you've previously set up a personal access token and would like to use the personal access token for verification, click Personal access token.
