php - Good single sign-on solution for Laravel

Question

I plan to introduce a single sign-on (SSO) to my Laravel 5 applications. Basically, I have two websites on different domains. The idea is simple: if I'm already authenticated on one of them, I don't need to sign in on the other.

I've been looking for a solution for a while now, but I would like to ask you: Do you know or can recommend a package or library to provide SSO to Laravel application?

Native PHP solutions are also welcome. Thanks!

You can use the SAML standard in order to solve your SSO needs.

Review this github repository that help you implement a SAML service provider: https://github.com/aacotroneo/laravel-saml2

If you need to implement a SAML Identity provider you can use simpleSAMLphp and use Lavarel database as authentication source. https://simplesamlphp.org/docs/stable/simplesamlphp-idp
