FO Ledger
Passkey required. No passwords.
Relying party app.monviso.cloud. A passkey is bound to its relying party, so a credential enrolled against one host cannot be used on another — enrolment here is a rehearsal unless this is the host the ledger will run on (§10).
Enrolling needs a five-minute window opened from the document plane with fo-ledger-open-enrolment, and the code it prints. A window is a deliberate act: nothing else opens one, and a restart opens nothing.
