Can the android application access the screen lock?

[Android Central Question]

I have an idea to make an application that, depending on the time, will put another password on the phone. Let's say the user has a password on the screen "777" and if on the clock is 22:22 or 15:15, the application will not accept the usual password, but will request another "555". Is it possible to do so?

Sure, bu who would want to use an app that could lock them out of their phone?
