# Which Problems Are Solved Improve performance by removing a GetUserByID call. The call also executed a Trigger on projections, which significantly impacted concurrent requests. # How the Problems Are Solved Token creation needs information from the user, such as the resource owner and access token type. For client credentials this is solved in a single search. By getting the user by username (`client_id`), the user details and secret were obtained in a single query. After that verification and token creation can proceed. For JWT profile it is a bit more complex. We didn't know anything about the user until after JWT verification. The verification did a query for the AuthN key and after that we did a GetUserByID to get remaining details. This change uses a joined query when the OIDC library calls the `GetKeyByIDAndClientID` method on the token storage. The found user details are set to the verifieer object and returned after verification is completed. It is safe because the `jwtProfileKeyStorage` is a single-use object as a wrapper around `query.Queries`. This way getting the public key and user details are obtained in a single query. # Additional Changes - Correctly set the `client_id` field with machine's username. # Additional Context - Related to: https://github.com/zitadel/zitadel/issues/8352
