Laravel SSO single user authentication?

Question

API

Tell me how you can implement a single entry point on Laravel.
The situation is as follows:
There are two projects on Laravel, and so I want to separate the authentication server (where the user tables are stored).
If I am authorized on the first site, I am immediately authorized on the second site as well.
How it is implemented within Laravel.

Answer 1

1) You need the same APP_KEY
2) Write the session to the database
3) Use one database for the connection.
4) Session key should also be the same

Answer 2

There are several options
- First , you create a central authentication server, where you give your clients a token, now you can implement auth through your CA in any site and the user can log in with one login and password. In particular, on Laravel you will need to create a custom auth
- Second - if you need the user to log in immediately, then on the n1 site you can give the cookie to the client, on the n2 site you can receive these cookies and check them on the n1 site. In particular, this is easy to do through middleware
