The Git web interface now allows enabling Two Factor authentication using a TOTP token. This is also now integrated into the existing Teknik TFA, so when you enable/disable it from the Teknik Settings page, it will propagate to the Git service as well.
In order to enable it for Git, you will need to enable TFA from your Teknik Settings page. If you already have it enabled in Teknik, you will need to disable it then re-enable it in order for it to propagate to the git service.
Let me know if you have any issues!
