Change Gitlab password
There's two alternative ways.
Both alternatives requires terminal or ssh to the server.
Alternative 1
Tested by me on a Raspberry Pi.
gitlab-rails console production
user = User.where(id: 1).first
user.password = 'your secret'
user.password_confirmation = 'your secret'
user.save
exit
You can read about how to setup GitLab on a Raspberry Pi here.
Alternative 2
The official docs way.
gitlab-rake "gitlab:password:reset[root]"
