Hold a Traveler’s gate-pass QR in the frame. It verifies against the public record —
no login, no account. A live pass is signed by the holder’s own key and refreshes every 15s,
so a screenshot can’t get anyone in.
Set once at the door — then a pass for another event won’t open this gate.
Scanning never needs a login. Punching deactivates a one-time pass, so it’s
recorded — date, time, gate, and your name — signed with your own key. Your phrase is
the whole sign-in: no username, no password, nothing typed but the words. Gate-crew access is
issued by the organizer ahead of time; there is nothing to create here. If you don’t
have a phrase, ask the organizer to issue you a Gate Staff credential.
