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

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

Note: As of March 2023, GitHub required all users who contribute code on GitHub.com to enable one or more forms of two-factor authentication (2FA). If you were in an eligible group, you would have received a notification email when that group was selected for enrollment, marking the beginning of a 45-day 2FA enrollment period, and you would have seen banners asking you to enroll in 2FA on GitHub.com. If you didn't receive a notification, then you were 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.
