Configuration 

Configuration happens at three levels:

  1. Extension settings -- Global defaults (algorithm, challenge TTL, rate limiting)
  2. Site configuration -- Per-site RP ID and origin
  3. TypoScript -- Plugin view settings and page UIDs
  4. Plugin FlexForm -- Per-plugin switches on the content element

Plugin FlexForm 

The login plugin carries one switch on the content element itself:

settings.discoverableEnabled

settings.discoverableEnabled
type

boolean

Default

enabled

Allow login without entering a username: the passkey identifies the user. This also switches WebAuthn Conditional UI — with it enabled the browser offers the passkey directly in the username field's autofill menu, which is the entry point most returning users reach for. Turn it off to require a username before a passkey is accepted.
