Single-use PIN

A single-use PIN is a short numeric code tied to one person and one purpose, used to authenticate an action such as clocking in without a full password.

En contexte

PINs are a low-friction way to confirm identity for frequent, quick actions where typing a long password is impractical: exactly the case at a time clock used many times a day. On their own, short PINs are weak, because they can be shared or guessed; they become meaningful when combined with another factor, such as binding the PIN to a specific device so it cannot travel to another phone.

Relation avec BriefQR

BriefQR pairs each operator's PIN with device binding, so the PIN only works from that person's registered device. That keeps clock-in fast while making shared logins and buddy punching far harder.
