One-time recovery codes are a common multi-factor authentication (MFA)
backup method, letting users access their account if they lose other MFA
devices. Support for recovery codes can also reduce support burden for
users locked out of their accounts and provide a more secure and
reliable form of verification than security questions.
# Which Problems Are Solved
Zitadel currently lacks support for recovery codes.
# How the Problems Are Solved
This PR partially addresses recovery code support in Zitadel.
Importantly, it adds recovery codes as a new 2FA `Factor` and an
additional `Check` type for the Session API.
```
Example recovery code flow:
1. User generates N new recovery codes using `POST /v2/users/{user_id}/recovery_codes`
2. Zitadel hashes and stores these codes and returns the un-hashed codes in the response
3. User creates new session with an additional check: `recoveryCode`
4. Code is checked against hash and, if valid, cannot be used again
5. User attempts to adds N more codes using the same endpoint
6. If `remaining_codes + N <= RecoveryCodes->MaxCount` config value, then recovery codes are added in addition to original codes
7. User can remove all recovery codes using `DEL /v2/users/:userId/recovery_codes`
```
This PR adds:
- [x] Session recovery_code check support on `POST+PATCH /v2/sessions`
endpoints
- [x] Adds `mfa_recovery_code_checked_at` column (default null) to
`projections.sessions8` table
- [x] Support for `SECOND_FACTOR_TYPE_RECOVERY_CODES` as available 2FA
method on login policy
- [x] Support for importing recovery codes in /import code
Missing, will _not_ implement in this PR:
- [ ] Admin console support for displaying Recovery Code settings for
user(s)
- [ ] Zitadel Typescript login support for recovery codes
TODO:
- [x] Additional unit and integration tests
- [x] Error translations

# 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

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

# 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.
