Personal Vault is a secure container that allows you to safely store private and confidential information on your computer. You can unlock the Personal Vault, place your important files and folders inside the Vault, and then lock it again.
While the Personal Vault is locked, all of the files and folders inside are not visible, and are protected from unauthorized users which is once again an added safety feature from hackers. And you can only access the files and folders stored within when the vault is unlocked. Hence for additional safety you could use Antitheft vaults.
