The FastPass is for one-time use only: if you've lost it or it's already been used, ask the host to resend the invitation.

The Munily FastPass is a single-use access code for each entry. If you lost the invitation (for example, you changed your phone and no longer have the message or chat) or the FastPass has already been used, you cannot reuse the same pass. In that case, you must ask the person who invited you (the host resident) to generate and send you a new invitation or access code via the app Munily. With the new invitation, you’ll receive another valid QR code for entry.
