How can I make my lockout time stack? If anyone has ever used an IPhone (Or tried to mess with someone else's - yes, I'm looking at you) you may be aware the the lockout timer scales with each fail after 5 attempts.

I want to do this on android, preferably Without root. anyone know how?

Edit On IPhone, after 5 failed passcode attempts, you are locked out for a minute. If you keep failing, it escalates (it will go up to 5 mins, then 15, then 60) I basically want to replicate that behaviour on android, where its 30 seconds lockout (and does not go up in time)
This feature is rate limiting
 and is done to prevent Brute Force Attack

This being a core security feature , it can be changed at OS level ( if at all ) and certainly would not be possible  without root

While I could not find reference to PIN / password rate limiting, you can see the Compatibility Definition Document 
(CSD ) mandating that for finger print recognition, specifying the number of attempts and duration. See 
How can I limit the number of fingerprint attempts before fallback to other login type?
