# Which Problems Are Solved
Currently ZITADEL supports RP-initiated logout for clients. Back-channel
logout ensures that user sessions are terminated across all connected
applications, even if the user closes their browser or loses
connectivity providing a more secure alternative for certain use cases.
# How the Problems Are Solved
If the feature is activated and the client used for the authentication
has a back_channel_logout_uri configured, a
`session_logout.back_channel` will be registered. Once a user terminates
their session, a (notification) handler will send a SET (form POST) to
the registered uri containing a logout_token (with the user's ID and
session ID).
- A new feature "back_channel_logout" is added on system and instance
level
- A `back_channel_logout_uri` can be managed on OIDC applications
- Added a `session_logout` aggregate to register and inform about sent
`back_channel` notifications
- Added a `SecurityEventToken` channel and `Form`message type in the
notification handlers
- Added `TriggeredAtOrigin` fields to `HumanSignedOut` and
`TerminateSession` events for notification handling
- Exported various functions and types in the `oidc` package to be able
to reuse for token signing in the back_channel notifier.
- To prevent that current existing session termination events will be
handled, a setup step is added to set the `current_states` for the
`projections.notifications_back_channel_logout` to the current position
- [x] requires https://github.com/zitadel/oidc/pull/671
# Additional Changes
- Updated all OTEL dependencies to v1.29.0, since OIDC already updated
some of them to that version.
- Single Session Termination feature is correctly checked (fixed feature
mapping)

# Which Problems Are Solved
Twilio supports a robust, multi-channel verification service that
notably supports multi-region SMS sender numbers required for our use
case. Currently, Zitadel does much of the work of the Twilio Verify (eg.
localization, code generation, messaging) but doesn't support the pool
of sender numbers that Twilio Verify does.
# How the Problems Are Solved
To support this API, we need to be able to store the Twilio Service ID
and send that in a verification request where appropriate: phone number
verification and SMS 2FA code paths.
This PR does the following:
- Adds the ability to use Twilio Verify of standard messaging through
Twilio
- Adds support for international numbers and more reliable verification
messages sent from multiple numbers
- Adds a new Twilio configuration option to support Twilio Verify in the
admin console
- Sends verification SMS messages through Twilio Verify
- Implements Twilio Verification Checks for codes generated through the
same

# Which Problems Are Solved
ZITADEL currently selects the instance context based on a HTTP header
(see https://github.com/zitadel/zitadel/issues/8279#issue-2399959845 and
checks it against the list of instance domains. Let's call it instance
or API domain.
For any context based URL (e.g. OAuth, OIDC, SAML endpoints, links in
emails, ...) the requested domain (instance domain) will be used. Let's
call it the public domain.
In cases of proxied setups, all exposed domains (public domains) require
the domain to be managed as instance domain.
This can either be done using the "ExternalDomain" in the runtime config
or via system API, which requires a validation through CustomerPortal on
zitadel.cloud.
# How the Problems Are Solved
- Two new headers / header list are added:
- `InstanceHostHeaders`: an ordered list (first sent wins), which will
be used to match the instance.
(For backward compatibility: the `HTTP1HostHeader`, `HTTP2HostHeader`
and `forwarded`, `x-forwarded-for`, `x-forwarded-host` are checked
afterwards as well)
- `PublicHostHeaders`: an ordered list (first sent wins), which will be
used as public host / domain. This will be checked against a list of
trusted domains on the instance.
- The middleware intercepts all requests to the API and passes a
`DomainCtx` object with the hosts and protocol into the context
(previously only a computed `origin` was passed)
- HTTP / GRPC server do not longer try to match the headers to instances
themself, but use the passed `http.DomainContext` in their interceptors.
- The `RequestedHost` and `RequestedDomain` from authz.Instance are
removed in favor of the `http.DomainContext`
- When authenticating to or signing out from Console UI, the current
`http.DomainContext(ctx).Origin` (already checked by instance
interceptor for validity) is used to compute and dynamically add a
`redirect_uri` and `post_logout_redirect_uri`.
- Gateway passes all configured host headers (previously only did
`x-zitadel-*`)
- Admin API allows to manage trusted domain

* handle all errors in defer
* do not fail auth request on error
the oauth2 Go client automagically retries on any error. If we fail the auth request on the first error, the next attempt will always fail with the Errors.AuthRequest.NoCode, because the auth request state is already set to failed.
The original error is then already lost and the oauth2 library does not return the original error.
Therefore we should not fail the auth request.
Might be worth discussing and perhaps send a bug report to Oauth2?

This implementation increases parallel write capabilities of the eventstore.
Please have a look at the technical advisories: [05](https://zitadel.com/docs/support/advisory/a10005) and [06](https://zitadel.com/docs/support/advisory/a10006).
The implementation of eventstore.push is rewritten and stored events are migrated to a new table `eventstore.events2`.
If you are using cockroach: make sure that the database user of ZITADEL has `VIEWACTIVITY` grant. This is used to query events.

This fix provides a possibility to pass a domain on the session, which
will be used (as rpID) to create a passkey / u2f assertion and
attestation. This is useful in cases where the login UI is served under
a different domain / origin than the ZITADEL API.
