OAuth - 2025 updated

OAuth (Open Authorization) is a widely used authorization framework that enables secure access delegation, allowing third-party applications to interact with user data without exposing sensitive credentials. Designed to enhance security and user convenience, OAuth operates by granting applications limited access to resources on behalf of users through access tokens, rather than requiring direct authentication with usernames and passwords. The protocol follows a token-based authentication model, where users authenticate with an authorization server, which then issues an access token that applications use to request data from a resource server. OAuth 2.0, the most commonly implemented version, supports various grant types, including Authorization Code Grant, Implicit Grant, Client Credentials Grant, and Resource Owner Password Credentials Grant, each tailored for different use cases. One of the key advantages of OAuth is its ability to enhance security by minimizing credential exposure, reducing the risk of password leaks and unauthorized access.
