After you configure 2FA via a TOTP mobile app, you can add a security key that supports the FIDO U2F standard to use for two-factor authentication on GitHub Enterprise.
Note: FIDO U2F authentication is currently only available for the Chrome browser.
- You must have already configured 2FA via a TOTP mobile app.
- Ensure that you have a FIDO U2F compatible security key inserted into your computer.
- In the upper-right corner of any page, click your profile photo, then click Settings.
In the user settings sidebar, click Security.
Under two-factor authentication, click Edit.
Under Security keys, click Register new device.
- Type a nickname for the security key, then click Add.
When prompted, touch your security key to have it authenticate against GitHub Enterprise.
If you're authenticating to GitHub Enterprise on an Android phone, you can use your FIDO U2F compatible security key and Google Authenticator to sign into your account with Near Field Communication (NFC).
Download your recovery codes and save them in a safe place, such as a password manager. Your recovery codes are to be used in the event you lose access to your account.
