# Which Problems Are Solved
When retrieving the information of an IdP intent, depending on the IdP
type (e.g. Apple), there was issue when mapping the stored (event)
information back to the specific IdP type, potentially leading to a
panic.
# How the Problems Are Solved
- Correctly initialize the user struct to map the information to.
# Additional Changes
none
# Additional Context
- reported by a support request
- needs backport to 3.x and 2.x
# Which Problems Are Solved
Some OAuth2 and OIDC providers require the use of PKCE for all their
clients. While ZITADEL already recommended the same for its clients, it
did not yet support the option on the IdP configuration.
# How the Problems Are Solved
- A new boolean `use_pkce` is added to the add/update generic OAuth/OIDC
endpoints.
- A new checkbox is added to the generic OAuth and OIDC provider
templates.
- The `rp.WithPKCE` option is added to the provider if the use of PKCE
has been set.
- The `rp.WithCodeChallenge` and `rp.WithCodeVerifier` options are added
to the OIDC/Auth BeginAuth and CodeExchange function.
- Store verifier or any other persistent argument in the intent or auth
request.
- Create corresponding session object before creating the intent, to be
able to store the information.
- (refactored session structs to use a constructor for unified creation
and better overview of actual usage)
Here's a screenshot showing the URI including the PKCE params:
# Additional Changes
None.

- This PR replaces the existing PR (#8228) of @doncicuto. The base he
did was cherry picked. Thank you very much for that!

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.
