Feature description

Add DuressPassword feature.

Hello, pls add DuressPassword feature (wipe phone data when DuressPassword entered). On most firmwares keyboards can work on lock screen and you can do it. You can use

DevicePolicyManager.wipeData(flags);

or if target sdk >=34 , this may not work and you can use instead it:

DevicePolicyManager.setMaximumFailedPasswordsForWipe(AdminReceiver, 1);

before send incorrect (Duress) password to system.

You need for first variant:

     <uses-policies>
       <wipe-data />
    </uses-policies>

and target sdk <=33

For second:

       <uses-policies>
        <wipe-data />
        <watch-login/>
      </uses-policies> 

and any target sdk.

To store duress password just use hash , for example sha256 or Argon.

Example how to do it you can see via this apps:
DuressKeyboard (target sdk<=33):

DuressKeyboardLite (target sdk>=34 and you can use this example for any sdk 8+ if you want):
