Special pin code for the mobile app to log out of the account

[Ilyntiy]

I would like to suggest a feature for a mobile application. It is simple, but it will increase privacy many times over.
The app has a pin code for access. You can make another pin code, which when entered exits the account and erases the data.
If you are forced to log in to the app you can enter a special pin code that will log out from your account and your data will remain safe.
