# 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. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
