# Which Problems Are Solved
TOTP codes could be reused, violating [RFC 6238, section
5.2](https://datatracker.ietf.org/doc/html/rfc6238#section-5.2).
# How the Problems Are Solved
Transmitted codes are now recorded in each success event. As the codes
amount to secrets, they are not stored verbatim but as a randomly salted
HMAC-SHA256 (`crypto.HMACValue`). Each value gets a fresh random salt,
so an equal code always produces a different stored value and two
entries can never be recognized as being derived from the same code.
This is deliberately not a replacement for proper secret storage: with
the salt stored alongside the hash and a 6 digit payload, anyone with
event access can brute-force the code in milliseconds. That is
acceptable here because a code is worthless once its window has passed.
The `HMACValue` doc comment states the same.
TOTP codes are low-entropy (6 digits), pseudo random codes. Therefore it
is possible for the same code to be generated more than once over the
lifetime of a user. In order to prevent the (unlikely) case where users
login with large time intervalls and a generated code may be equal to
the one last used a long time ago, we only check for codes used within
the recent period window.
A simpler implementation would be simply storing the latest consumed
step, but the TOTP library does not return this value. Because of the
allowed skew there are always 3 steps within the validation window, so
we can't calculate the current step based on time alone. The retained
history spans one period more than the validation window: validity is
decided by the app server's clock, while the stored events carry the
database clock, and the extra period absorbs the drift between them.
**Note:** a reused code pushes a distinct
`user.human.mfa.otp.check.reused` event, not a failed check event. A
replay therefore stays observable through the Events API without
counting towards the lockout policy. Otherwise anyone who captured a
code could replay it to lock the user out.

- Read only the latest events in recheck query

## Which Problems Are Solved
- Add comprehensive Arabic language support to ZITADEL
## How the Problems Are Solved
- Added full Arabic translation files for the login UI, console, and
notification (yaml and json).
- Ensured all keys match the latest English reference files to avoid
missing or inconsistent entries.
- Updated the localization loader to include `ar` as a supported
language.

# Which Problems Are Solved
Naming inconsistency w.r.t the usage of Given Name / Family Name instead
of First Name / Last Name
# How the Problems Are Solved
* By replacing given and family names with first and last names in UI
and docs (not in the API definitions)
* Updated translations in multiple languages to first and last names
instead of given/family names
# Additional Changes
* Add `internal/**/*.yaml` path to the nx sources input to rebuild the
binary upon changes to these files
* Fix failing unit tests in `user_notifier_legacy_test.go` by updating
`Passwordless` with `Passkey`

# 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.
# Additional Changes
None.

Hello everyone,
To support Korean-speaking users who may experience challenges in using
this excellent tool due to language barriers, I have added Korean
language support with the help of ChatGPT.
I hope that this contribution allows ZITADEL to be more useful and
accessible to Korean-speaking users.
Thank you.
