Изменение метода двухфакторной проверки подлинности

You can reconfigure your two-factor authentication (2FA) settings or add new 2FA methods without disabling 2FA entirely, allowing you to keep both your recovery codes and your membership in organizations that require 2FA.

Changing an existing two-factor authentication method

You can configure a different authenticator app or change your phone number, without disabling 2FA or creating a new set of recovery codes.

Changing the TOTP app

You can change the time-based one-time password (TOTP) application you use to generate authentication codes.

1. In the upper-right corner of any page on GitHub, click your profile photo, then click Settings.

2. In the "Access" section of the sidebar, click Password and authentication.

3. In "Two-factor methods", find the method you want to modify. Next to that method, click Edit. If you have multiple methods configured, select , then click Edit.

   

4. Under "Scan the QR code", do one of the following:

   • Scan the QR code with your mobile device's app. After scanning, the app displays a six-digit code that you can enter on GitHub Enterprise Cloud.
   • If you can't scan the QR code, click setup key to see a code, the TOTP secret, that you can manually enter in your TOTP app instead.
   

5. The TOTP application saves your account on GitHub.com and generates a new authentication code every few seconds. On GitHub Enterprise Cloud, type the code into the field under "Verify the code from the app."

6. Click Save to save the method to your GitHub account.

If you are unable to scan the setup QR code or wish to setup a TOTP app manually and require the parameters encoded in the QR code, they are:

• Type: TOTP
• Label: GitHub:<username> where <username> is your handle on GitHub, for example monalisa
• Secret: This is the encoded setup key, shown if you click "Setup key" during configuration
• Issuer: GitHub
• Algorithm: The default of SHA1 is used
• Digits: The default of 6 is used
• Period: The default of 30 (seconds) is used

Changing the SMS number

You can change the phone number you use to receive authentication codes via SMS.

1. In the upper-right corner of any page on GitHub, click your profile photo, then click Settings.

2. In the "Access" section of the sidebar, click Password and authentication.

3. In "Two-factor methods", find the method you want to modify. Next to that method, click Edit. If you have multiple methods configured, select , then click Edit.

   

4. Complete the CAPTCHA challenge, which helps protect against spam and abuse.

5. Under "Verify account", select your country code and type your mobile phone number, including the area code. When your information is correct, click Send authentication code.

6. You'll receive a text message with a security code. On GitHub Enterprise Cloud, type the code into the field under "Verify the code sent to your phone" and click Continue.

   • If you need to edit the phone number you entered, you'll need to complete another CAPTCHA challenge.

7. Click Save to save the method to your GitHub account.

Adding additional two-factor authentication methods

We recommend adding more than one 2FA method to your account. This ensures that you can still sign in to your account, even if you lose one of your methods.

In addition to adding multiple 2FA methods, we strongly recommend setting up multiple recovery methods to avoid losing access to your account. For more information, see Configuring two-factor authentication recovery methods.

Adding a TOTP app

3. In "Two-factor methods", find the method you want to add. Next to that method, click Add.
