What is OAuth 2.0?
OAuth 2.0
An open standard for access delegation, commonly used as a way for Internet users to grant websites or applications access to their information on other websites but without giving them the passwords.
OAuth 2.0 roles
-
Resource Owner: the entity that can grant access to a protected resource. Typically this is the end-user.
-
Resource Server: the server hosting the protected resources. This is the API you want to access.
-
Client: the app requesting access to a protected resource on behalf of the Resource Owner.
- Authorization Server: the server that authenticates the Resource Owner, and issues Access Tokens after getting proper authorization. In this case, Auth0.
