Auth and session

I am implementing a ticket selling website. This website is going to use an authentication system made by myself. I want to make it because I believe that it's good to have done to it once at least, and I also want to understant how to use sessions, TDD and the auth()/Auth helper/class. I am probably having an Auth controller for the CMS and another for the users of the site. I don't know properly how implement those yet and that's why I'd like to know if anyones has references of where to learn about sessions and auth.

I am after a manner to to authenticate a user and store it in a session and also to pass a user token to the fronend so that axios requests can use the token on the header for routes that require authentication. I don't how to do it, that's why I am coming to you.
