I have an account on bitbucket.org that I created by signing up with my Google account. Now everytime I log in I just click "Log in with Google" and that's fine.
How can I access my repos from git command line? It requests me username and password. I have a username, but no password. How do I log in then?
You should do a one-time setup of creating an "App password" in Bitbucket web UI with permissions to at least read your repositories and then use it in the command line.
