# Which Problems Are Solved
Zitadel never stored or returned the requested `response_mode` in oidc
Auth Requests. This caused the oidc library to fallback to the default
based on the response_type.
# How the Problems Are Solved
- Store the `response_mode` in the Auth request repo
- Store the `response_mode` in the Auth request v2 events
- Return the `resonse_mode` from the Auth Request v1 and v2
`ResponseMode()` methods. (Was hard-coded to an empty string)
# Additional Changes
- Populate the `response_modes_supported` to the oidc Discovery
Configuration. When it was empty, the standard specifies the default of
`query` and `fragment`. However, our oidc library also supports
`form_post` and by this fix, zitadel now also supports this.
# Additional Context
- Closes#6586

This pr upgrades oidc to v3 . Function signature changes have been migrated as well. Specifically there are more client calls that take a context now. Where feasable a context is added to those calls. Where a context is not (easily) available context.TODO() is used as a reminder for when it does.

This PR changes the information stored on the SessionLinkedEvent and (OIDC Session) AddedEvent from OIDC AMR strings to domain.UserAuthMethodTypes, so no information is lost in the process (e.g. authentication with an IDP)
This PR starts the OIDC implementation for the API V2 including the Implicit and Code Flow.
