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

You can set up your account on GitHub.com to require an authentication code in addition to your password when you sign in.

Note: Starting in March 2023 and through the end of 2023, GitHub will gradually begin to require all users who contribute code on GitHub.com to enable one or more forms of two-factor authentication (2FA). If you are in an eligible group, you will receive a notification email when that group is selected for enrollment, marking the beginning of a 45-day 2FA enrollment period, and you will see banners asking you to enroll in 2FA on GitHub.com. If you don't receive a notification, then you are not part of a group required to enable 2FA, though we strongly recommend it.

For more information about the 2FA enrollment rollout, see this blog post.
