HI @grehce it looks like the request here is for the password associated with your ssh key, not an access token or account password. I can tell this is the case because its requesting password for user git, not your username, and the error message in screenshot 2 is: git@gitlab.com: Permission denied (publickey).
Did you set a password when creating the SSH key affiliated with your GitLab account? If so, can you try entering that password in the prompt in your first screenshot?
Let us know how it goes!
