This repository shall provide solutions for problems with your 2FA authenticator app when adding GitLab OTP
- Update the timezone within your GitLab profile settings to match the timezone of the device your 2FA app runs on (this was my problem actually)
- Synchronize the time of your 2FA app if possible (or activate time correction for the GitLab 2FA)
- In some cases it seems like the grace period before you having to set up the 2FA for a repository (or the whole instance) affects the 2FA app. If nothing else works, try to increase it
