 This further configuration is not required for Google authentication to function but it is strongly recommended. Taking these steps will increase usability for users by providing a little more recognition and branding.
 
 At this point, when users first try to authenticate to your GitLab installation with Google they will see a generic application name on the prompt screen.

"Project Default Service Account" isn't very recognizable and may confuse or cause users to be concerned. This is easily changeable.
