OAuth2 is an authorization framework that grants restricted access to the protected resource. In this framework, the client delegates authentication to an authorization server and obtains the access token to grant access to an application or a web service. The client can be web applications, mobile phones, hand-held devices, and desktop applications.
While using the OAuth2 framework, the OAuth server validates users and grants access to the corresponding account of Privileged Account Manager. Here, Privileged Account Manager serves as the OAuth2 client.
