Closes #10727
Closes #10577
# Which Problems Are Solved
This PR fixes the organization domain scope when provided and introduces
a deep-link feature for external applications, that sends users directly
into passkey registration flow using either session-based or sessionless
flows. Previously, the `/passkey/set` page only supported session-based
registration, limiting external application integration scenarios.
The `/passkey/set` page now supports:
- `code` search parameter for automatic passkey registration
- `userId` parameter for sessionless flows (similar to `/verify` and
`/password/set` pages)
- Auto-submit functionality when verification codes are provided
# How the Problems Are Solved
The organization scope is fixed by the backend handler for OIDC flows,
now correctly submitting a `suffix` queryparam to the /loginname url
which is used to show in the input field.
The passkey code support is implemented by support multiple integration
patterns:
- **Session-based**: `/passkey/set?sessionId=123&code=abc123` (existing
flow)
- **Sessionless**: `/passkey/set?userId=123456&code=abc123` (new flow)
External Application Integration Flow
1. External app triggers passkey register and obtains code
2. User verification link containing `userId`, `code` and `id`
parameters
3. User clicks link → `/passkey/set?userId=123&code=abc&id=123`
4. Page loads user information using `userId` parameter
5. Auto-submit triggers passkey registration when `code` and `id` is
present
6. User completes WebAuthn request
7. Passkey is registered and user continues authentication flow
This enables external applications to seamlessly integrate passkey
registration into their user onboarding
