Have you considered adding GitLab authentication?

[bruntib]

GitLab is not in focus for us, currently. However, the infrastructure is prepared for it.

@bruntib I might give GitLab authentication a shot and open a merge request if things go well - if that’s okay with you.

Sure, all contributions are welcome! Thank you in advance!
