The OAuth spec [defines two types of client](https://datatracker.ietf.org/doc/html/rfc6749#section-2.1), confidential and public. Previously Gitea assumed all clients to be confidential. > OAuth defines two client types, based on their ability to authenticate securely with the authorization server (i.e., ability to > maintain the confidentiality of their client credentials): > > confidential > Clients capable of maintaining the confidentiality of their credentials (e.g., client implemented on a secure server with > restricted access to the client credentials), or capable of secure client authentication using other means. > > **public > Clients incapable of maintaining the confidentiality of their credentials (e.g., clients executing on the device used by the resource owner, such as an installed native application or a web browser-based application), and incapable of secure client authentication via any other means.** > > The client type designation is based on the authorization server's definition of secure authentication and its acceptable exposure levels of client credentials. The authorization server SHOULD NOT make assumptions about the client type. https://datatracker.ietf.org/doc/html/rfc8252#section-8.4 > Authorization servers MUST record the client type in the client registration details in order to identify and process requests accordingly. Require PKCE for public clients: https://datatracker.ietf.org/doc/html/rfc8252#section-8.1 > Authorization servers SHOULD reject authorization requests from native apps that don't use PKCE by returning an error message Fixes #21299 Co-authored-by: wxiaoguang <wxiaoguang@gmail.com> Co-authored-by: Lunny Xiao <xiaolunwen@gmail.com>
