I have two-factor authentication (2FA) enabled on most of my accounts using an authenticator app. Recently, while installing the app on another Android device, I tried to change the backup password, but it didn't work. As a result, I lost access, had to disable 2FA, and re-enable it using a different authenticator app.
Setting up 2FA again wasn't a problem because I was still logged in to most of my accounts. However, I didn't have my GitLab recovery codes. GitLab offers only two ways to regain access: receiving a six-digit verification code via email or generating new recovery codes using an SSH key associated with the account.
Receiving a verification code via email is the easiest way to recover your account, but having an SSH key can be incredibly useful when receiving an email verification code isn't an option.
Whenever I configure GitLab in my local environment, I create an SSH key for authentication and commit signing, as I always sign commits in my repositories. I described this process in a previous page
Now you're signed in! Disable 2FA and re-enable it—and don't forget to save your recovery codes somewhere safe this time.
