The OAuth Provider extension surface let a grant handler drift from what it issued in two ways. The client-registration check honored a request-supplied grant type while issuance used the provider-bound grant, so a handler could authenticate a client for a permissive grant and mint under a stricter one. And a client-authentication strategy returned the client record the provider then authorized against, so a strategy could supply a client's grants, scopes, or enabled state. The provider-bound grant is now the sole authority for the registration check, and grantType is removed from OAuthClientAuthenticationRequest. A strategy proves only the client id it authenticated (plus an optional confirmation); the provider resolves and authorizes the client record itself via getClient. The strategy result type is now OAuthClientAuthenticationResult.
Better Auth
Better Auth is a framework-agnostic authentication (and authorization) framework for TypeScript. It provides a comprehensive set of features out of the box and includes a plugin ecosystem that simplifies adding advanced functionalities with minimal code in a short amount of time. Whether you need 2FA, multi-tenant support, or other complex features, it lets you focus on building your actual application instead of reinventing the wheel.
Why Better Auth
Authentication in the TypeScript ecosystem is a half-solved problem. Other open-source libraries often require a lot of additional code for anything beyond basic authentication. Rather than just pushing third-party services as the solution, I believe we can do better as a community—hence, Better Auth.
