What Is OAuth?

OAuth is an open standard for access delegation commonly used for token-based authentication.

It allows third-party services to exchange information without sharing passwords.

OAuth enables users to grant limited access to their resources on one site to another site without exposing their credentials.

The protocol is widely used by major platforms like Google, Facebook, and Twitter for secure authorization.

OAuth 2.0 is the most widely adopted version, providing improved security and flexibility.

It involves roles such as resource owner, client, authorization server, and resource server.

The process typically includes obtaining an access token that grants permission to access specific resources.

OAuth is essential for modern web applications that require secure and user-friendly authentication methods.
