Detailed explanation-1: -Despite having auth in the name, OAuth is not an authentication mechanism. Instead, it provides authorization services to determine which users have access to various corporate resources. OAuth is used alongside OpenID, an authentication mechanism.

Detailed explanation-2: -OAuth doesn’t share password data but instead uses authorization tokens to prove an identity between consumers and service providers. OAuth is an authentication protocol that allows you to approve one application interacting with another on your behalf without giving away your password.

Detailed explanation-3: -OAuth (pronounced “oh-auth”) is a technological standard that allows you to share information between services without exposing your password. It’s a widely-adopted standard that’s used by developers of websites and apps, and you probably use services every day that utilize OAuth.

Detailed explanation-4: -OAuth is not authentication. It’s an authorization protocol, or, better yet, a delegation protocol. It’s for this reason that identity protocols such as OpenID Connect exist and legacy protocols such as SAML use extension grants to link authentication and delegation.
