# Which Problems Are Solved
The current login will always prefer external authentication (through an
IdP) over local authentication. So as soon as either the user had
connected to an IdP or even when the login policy was just set up to
have an IdP allowed, users would be redirected to that IdP for
(re)authentication.
This could lead to problems, where the IdP was not available or any
other error occurred in the process (such as secret expired for
EntraID).
Even when local authentication (passkeys or password) was allowed for
the corresponding user, they would always be redirected to the IdP
again, preventing any authentication. If admins were affected, they
might not even be able to update the client secret of the IdP.
# How the Problems Are Solved
Errors during the external IdP flow are handled in an
`externalAuthFailed` function, which will check if the organisation
allows local authentication and if the user has set up such.
If either password or passkeys is set up, the corresponding login page
will be presented to the user. As already with local auth passkeys is
preferred over password authentication.
The user is informed that the external login failed and fail back to
local auth as an error on the corresponding page in a focused mode. Any
interaction or after 5 second the focus mode is disabled.

# Which Problems Are Solved
There are some problems related to the use of CockroachDB with the new
notification handling (#8931).
See #9002 for details.
# How the Problems Are Solved
- Brought back the previous notification handler as legacy mode.
- Added a configuration to choose between legacy mode and new parallel
workers.
- Enabled legacy mode by default to prevent issues.
# Additional Changes

# Which Problems Are Solved
The current handling of notification follows the same pattern as all
other projections:
Created events are handled sequentially (based on "position") by a
handler. During the process, a lot of information is aggregated (user,
texts, templates, ...).
This leads to back pressure on the projection since the handling of
events might take longer than the time before a new event (to be
handled) is created.
# How the Problems Are Solved
- The current user notification handler creates separate notification
events based on the user / session events.
- These events contain all the present and required information
including the userID.
- These notification events get processed by notification workers, which
gather the necessary information (recipient address, texts, templates)
to send out these notifications.
- If a notification fails, a retry event is created based on the current
notification request including the current state of the user (this
prevents race conditions, where a user is changed in the meantime and
the notification already gets the new state).
- The retry event will be handled after a backoff delay. This delay
increases with every attempt.
- If the configured amount of attempts is reached or the message expired
(based on config), a cancel event is created, letting the workers know,
the notification must no longer be handled.
- In case of successful send, a sent event is created for the
notification aggregate and the existing "sent" events for the user /
session object is stored.
- The following is added to the defaults.yaml to allow configuration of
the notification workers:
```yaml
Notifications:
# The amount of workers processing the notification request events.
# If set to 0, no notification request events will be handled. This can be useful when running in
# multi binary / pod setup and allowing only certain executables to process the events.
Workers: 1 # ZITADEL_NOTIFIACATIONS_WORKERS
# The amount of events a single worker will process in a run.
BulkLimit: 10 # ZITADEL_NOTIFIACATIONS_BULKLIMIT
# Time interval between scheduled notifications for request events
RequeueEvery: 2s # ZITADEL_NOTIFIACATIONS_REQUEUEEVERY
# The amount of workers processing the notification retry events.
# If set to 0, no notification retry events will be handled. This can be useful when running in
# multi binary / pod setup and allowing only certain executables to process the events.
RetryWorkers: 1 # ZITADEL_NOTIFIACATIONS_RETRYWORKERS
# Time interval between scheduled notifications for retry events
RetryRequeueEvery: 2s # ZITADEL_NOTIFIACATIONS_RETRYREQUEUEEVERY
# Only instances are projected, for which at least a projection-relevant event exists within the timeframe
# from HandleActiveInstances duration in the past until the projection's current time
# If set to 0 (default), every instance is always considered active
HandleActiveInstances: 0s # ZITADEL_NOTIFIACATIONS_HANDLEACTIVEINSTANCES
# The maximum duration a transaction remains open
# before it spots left folding additional events
# and updates the table.
TransactionDuration: 1m # ZITADEL_NOTIFIACATIONS_TRANSACTIONDURATION
# Automatically cancel the notification after the amount of failed attempts
MaxAttempts: 3 # ZITADEL_NOTIFIACATIONS_MAXATTEMPTS
# Automatically cancel the notification if it cannot be handled within a specific time
MaxTtl: 5m # ZITADEL_NOTIFIACATIONS_MAXTTL
# Failed attempts are retried after a confogired delay (with exponential backoff).
# Set a minimum and maximum delay and a factor for the backoff
MinRetryDelay: 1s # ZITADEL_NOTIFIACATIONS_MINRETRYDELAY
MaxRetryDelay: 20s # ZITADEL_NOTIFIACATIONS_MAXRETRYDELAY
# Any factor below 1 will be set to 1
RetryDelayFactor: 1.5 # ZITADEL_NOTIFIACATIONS_RETRYDELAYFACTOR

# Which Problems Are Solved
As an administrator I want to be able to invite users to my application
with the API V2, some user data I will already prefil, the user should
add the authentication method themself (password, passkey, sso).
# How the Problems Are Solved
- A user can now be created with a email explicitly set to false.
- If a user has no verified email and no authentication method, an
`InviteCode` can be created through the User V2 API.
- the code can be returned or sent through email
- additionally `URLTemplate` and an `ApplicatioName` can provided for
the email
- The code can be resent and verified through the User V2 API
- The V1 login allows users to verify and resend the code and set a
password (analog user initialization)
- The message text for the user invitation can be customized
# Additional Changes
- `verifyUserPasskeyCode` directly uses `crypto.VerifyCode` (instead of
`verifyEncryptedCode`)
- `verifyEncryptedCode` is removed (unnecessarily queried for the code
generator)
# Additional Context
- closes#8310
- TODO: login V2 will have to implement invite flow:
