OAuth 2.0 is the industry-standard protocol for authorization and access delegation. It specifies a process for resource owners to authorize third-part access to their resources without sharing their credentials. OAuth facilitates fast and secure authentication and authorization for users to APIs, servers, devices and apps. It does this without sharing password information and instead uses access tokens to prove an identity, keeping user credentials safe.
