-# auth
-
-This package provides uses the [GoToSocial oauth2](https://github.com/gotosocial/oauth2) module (forked from [go-oauth2](https://github.com/go-oauth2/oauth2)) to provide [oauth2](https://www.oauth.com/) functionality to the GoToSocial client API.
-
-It also provides a handler/middleware for attaching to the Gin engine for validating authenticated users.

-// Package auth is a module that provides oauth functionality to a router.
-// It adds the following paths:
-//    /auth/sign_in
-//    /oauth/token
-//    /oauth/authorize
-// It also includes the oauthTokenMiddleware, which can be attached to a router to authenticate every request by Bearer token.
