Need Help for a Univeristy Project

Hello, I want to make an App such that it asks for a password from user. If user enters incorrect password, the app suspends the password for 2 mins. During this time, the user can not enter password. I created such app using screens but the problem is that if user closes and reopens the app, he can enter password even before the 2 mins time from the incorrect entry. Please tell me how can I add this feature that the app remembers the time even after being closed.

This can give you some idea to amplify you work
