An invite token behaves like a password: anyone holding it can use it. So design them with the same threat model—single-use (is_used = true after claim), time-limited (7-day default expiry), auditable (which admin generated it), and revocable (admin voids a leaked token). The audit trail is the only edge over a password: every token has a created_by_id and a claimed_by_id, so the entire invitation history lives in the database.
