About DuressUltimate
DuressUltimate is an Android security utility that can trigger a device-data wipe when a code of a chosen length is entered into the system lock-screen password field. It is designed for a password-protected phone and uses an attempts limit to keep the wipe trigger active. The code length must differ from the main password length, and the app counts an incorrect attempt only after more than four characters have been entered. The app adjusts the attempt limit dynamically while the password field is in use, with a configurable upper ceiling of one to five attempts. The supplied description says the limit remains at one while the app is idle and when the trigger-length code is being entered; while a different-length password is being entered, the limit is temporarily raised by two up to the ceiling. Device Admin and Accessibility permissions are required. Device Owner permission is optional for additional functions. The device must use a password screen lock, and biometrics and trust agents must be disabled for the described trigger to work. The app’s operation depends on Android’s lock-screen and permission behavior. Its intended purpose is to protect data when a person is compelled to unlock a device, but the configured outcome is destructive and can permanently erase data. DuressUltimate is a specialized security tool, not a backup or recovery app. The exact requirements and high consequence of the wipe make it important that users understand how the trigger behaves on their own device before relying on it.
