A Go package that adds OpenID Connect client support to the standard OAuth2 library.
go-oidc is a Go library that implements the OpenID Connect client protocol, enabling Go applications to authenticate users via identity providers like Google or Auth0. It extends the standard `golang.org/x/oauth2` package to handle OIDC-specific features such as ID token verification and provider discovery.
Go developers building web applications or services that require secure user authentication via third-party identity providers.
It provides a lightweight, standards-compliant way to add OIDC support to Go applications without implementing the protocol from scratch, leveraging the familiar OAuth2 package ecosystem.
A Go OpenID Connect client.
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Built as an extension to the standard `golang.org/x/oauth2` package, allowing developers to leverage familiar OAuth2 flows with minimal code changes, as shown in the README's configuration example.
Automatically fetches OIDC provider endpoints from an issuer URL, simplifying setup by eliminating manual configuration, demonstrated in the `oidc.NewProvider` call.
Verifies ID tokens with signature validation using JWKS, ensuring secure authentication without implementing crypto logic, as seen in the `verifier.Verify` method.
Allows straightforward extraction of user claims from verified tokens, enabling quick access to data like email, illustrated by the `idToken.Claims` function in the README.
The v3 update introduced breaking changes, such as altered import paths and return types (e.g., `NewRemoteKeySet`), which can cause migration headaches, as admitted in the README.
Focuses solely on OIDC client basics; lacks built-in support for advanced features like automatic token refresh or comprehensive error handling, requiring manual implementation.
Relies on OIDC providers being available for discovery and verification, introducing points of failure in distributed systems if providers are down or unreachable.
