You can set up your GitHub Enterprise account to require an authentication code in addition to your password when you sign in.
About two-factor authentication
Two-factor authentication, or 2FA, is an extra layer of security used when logging into websites or apps. With 2FA, you have to log in with your username and password and provide another form of authentication that only you know or have access to.
Configuring two-factor authentication
You can configure two-factor authentication using a mobile app. You can also add a security key using FIDO U2F.
Configuring two-factor authentication recovery methods
You can set up a variety of recovery methods to access your account if you lose your two-factor authentication credentials.
Accessing GitHub using two-factor authentication
With 2FA enabled, you'll be asked to provide your 2FA authentication code, as well as your password, when you sign in or authenticate to GitHub Enterprise.
Recovering your account if you lose your 2FA credentials
If you lose access to your two-factor authentication credentials, you can use your recovery codes, or another recovery option if you've set one up, to regain access to your account.
Disabling two-factor authentication for your personal account
If you disable two-factor authentication for your personal account, you may lose access to organizations you belong to.
