# 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.
