More options of user authentication and rights

Is your feature request related to a problem? Please describe.
At the moment, there's only one username/password combination to access the dashboard and if I want to give access to my team, anyone can change what they want and if someone leaves the team, I don't want to have to change the password every time.

Describe the solution you'd like
I think it would be interesting to add a "member" section to manage several users authorized to display the dashboard, to perform certain actions and also with an SSO connection with Google to restrict access and avoid the risk of password leakage.

Additional context
The same system as Sentry.
