PIN for every device

Hardware key managers provide the option to lock usage of the devices with short numeric PINs. These provide an essential layer of security against theft so that physical possession of a hardware key is not enough to activate the device. Hardware devices will wipe themselves after a certain number of incorrect PIN guesses, protecting against an attacker brute-forcing the PIN.

We recommend that Casa clients use the same PIN for every device to prevent confusion and accidental lock-out. We also highly recommend storing your PIN in a secure password manager to prevent losing it. For premium clients, Casa also offers the option of storing a copy of your PIN to further prevent loss.
