Línea de trabajo

The payload names no repository files; the work centres on the Android device-admin APIs it cites, DevicePolicyManager.wipeData and setMaximumFailedPasswordsForWipe, plus the uses-policies manifest entries and the target SDK limits. Start by deciding whether a keyboard app can legitimately hold device-admin rights, which is a design question for maintainers before any code. Done would mean a maintainer-approved design and a reviewed security model, not just a working wipe.

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):
https://github.com/pofesk0/lastcodeduresskeyboard

https://f-droid.org/packages/duress.keyboard

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

https://github.com/pofesk0/DuressKeyboardLite

https://f-droid.org/packages/duress.keyboard.lite

Why do you want this feature?

This feature need to help people under duress to wipe phone data by entering special panic code without unlock phone.
