Can an android app access the lock screen?

Question

Android

There is an idea to make an application that, depending on the time, will set a different password on the phone. Let's say the user has a password on the screen "555" and if it's 22:22 or 15:15 on the clock, the application will not accept the usual password, but will request another " 111". Is it possible to do so?

Answer 1

No.
