# Which Problems Are Solved Do not return an access token for implicit flow from v1 login, if the `response_type` is `id_token` # How the Problems Are Solved Do not create the access token event if if the `response_type` is `id_token`. # Additional Changes Token endpoint calls without auth request, such as machine users, token exchange and refresh token, do not have a `response_type`. For such calls the `OIDCResponseTypeUnspecified` enum is added at a `-1` offset, in order not to break existing client configs. # Additional Context - https://discord.com/channels/927474939156643850/1294001717725237298 - Fixes https://github.com/zitadel/zitadel/issues/8776
