I want implement Single signing OAauth 2.0 , in our case we use implement oauth in our server , not using any third party,
Run your own OAuth2 Server
when user login in one site then it allow to access another site without login using Single sign-on,
please share implementation step to achieve this functionality.
OAuth 2.0 won’t do what you want on its own; it just provides a “framework” of specifications you can use for different auth scenarios.
You want OpenID Connect. This is built on top of OAuth 2.0 and gives a clearly defined route for providing SSO. There’s a certified PHP library for doing most of the work.
