Is it possible to integrate Looker authentication with my application?

[pt1]

I am exploring the use of Looker, hosted on-premises, for my application.  My application has it's own custom user management.  Is it possible to have Looker, self-hosted, authenticate against my application using some sort of custom auth or something?  Or would I need to set up some sort of SAML / OpenID layer in front of my application that Looker could use?

Alternatively, is it possible to "authenticate" a user completely via the API, but without a password?  For example to make a call to the Looker API and get back an auth token that could be used for requests?

https://developers.looker.com/api/explorer/4.0/methods/ApiAuth/login_user does exactly what you want. You can have one service account that is used to get API authentication tokens for other users.
