What is the default username and password for the GitLab?

The default login for the GitLab is: root / (blank) (web-ui); admin / 5iveL!fe (web-ui); admin@local.host / 5iveL!fe (web-ui); root / 5iveL!fe (web-ui).

How do I change the default password on the GitLab?

Log in with the default credentials, then open the administration / user settings and set a strong, unique password. Leaving default credentials in place is a serious security risk — change them immediately on any production device.
