Hi Bob,

Thank you for contacting us. I'm not exactly sure what you mean when you ask about a PIN for unlocking mSecure. You can set a 4 number password, and that can be used for unlocking the app, but we don't recommend that due to how easy it is to crack a password that weak. Alternatively, if you are running mSecure 5, you should be able to set up Windows Hello, where you can unlock mSecure using face recognition or by setting up a PIN. That is definitely the more secure method for unlocking, though the 4 digit PIN for unlocking through Windows Hello is not very secure.

Are you using mSecure 5, and are you familiar with Windows Hello?
