CATMA is built on GitLab, which we use to manage your account and data.

Came from CATMA? Sign in with your CATMA username and password, and you'll be redirected back to CATMA once you're signed in.

Didn't come here from CATMA? Then signing in on this page will take you to GitLab itself, not to CATMA. To use CATMA, go to app-dev.catma.de, click "Sign In" and follow the steps.

Don't have a CATMA account yet? Click "Sign Up" at app-dev.catma.de first. You can't create an account on this page.

Signing in with Google only works if your CATMA account was created with the same email address.
