Features & Specs

  1. Delegated access without sharing credentials

    OAuth2 lets users grant third-party applications limited access to their resources without handing over their passwords. Access tokens stand in for credentials, so a compromised client exposes far less than a leaked username and password would.

  2. Scoped and limited permissions

    Tokens can be restricted to specific scopes, resources, and lifetimes, so applications receive only the access they need. Users and administrators can also revoke tokens at any time without changing the account password.

  3. Widely adopted industry standard

    OAuth2 is supported by major providers such as Google, Microsoft, GitHub, and Facebook, and by most identity platforms. This broad adoption means mature libraries, SDKs, tooling, and community knowledge are available for nearly every language and framework.

  4. Flexible grant types for many use cases

    The framework defines multiple flows, including Authorization Code (with PKCE), Client Credentials, and Device Code. These cover web apps, single-page apps, mobile apps, server-to-server communication, and input-constrained devices.

  5. Enables single sign-on and API ecosystem integration

    Combined with OpenID Connect, OAuth2 supports federated login and single sign-on across services. It also provides a consistent way to secure APIs and let third-party developers integrate with a platform in a controlled manner.
