What should I do if my users need to use a Latch-closed service, but they don´t have their device on hand to open it? A user can sign in to the Latch app from any mobile device. If they don´t have any device on hand, you can always override the Latch security layer and operate your service in your usual way ignoring the Latch status. Have more questions?
