Enable Fortify passkeys (laravel/passkeys) with the @laravel/passkeys
client. Users can sign in with a passkey, confirm sensitive actions with
one, and add, rename, and delete passkeys on the Profile page.
- Resolve the relying party for each request from the instance URL, then
APP_URL, then localhost. Passkey routes return 404 on other hosts.
- Add the is_passkey_enabled instance setting (Settings > Advanced).
- Use a hex user handle (laravel/passkeys-server#41).
- Rate limit the passkey routes by client IP.
- Record audit events for registered, verified, and deleted passkeys.
