Securing your account with two-factor authentication (2FA)

Two-factor authentication (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.

You can choose among multiple options to add a second source of authentication to your account.

You can set up a variety of recovery methods to access your account if you lose your two-factor authentication credentials.

With 2FA enabled, you'll be asked to provide your 2FA authentication code, as well as your password, when you sign in to GitHub Enterprise Server.

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.

You can change two-factor authentication (2FA) method without disabling 2FA entirely.

If you disable two-factor authentication for your personal account, you may lose access to organizations you belong to.
