DuressUltimate

Duress Ultimate - This is an application for being prepared for unexpected situations, which erases all data from the phone when entering and submitting any code of a length specified by you for reset instead of the password on the lock screen. It can also delete data when the attempt limit is exhausted.

Here's how it works:

After receiving all permissions, it sets the minimum unlock attempt limit for data reset

It temporarily increases this limit by 2 (up to the total value of 1–5 specified by you) when entering any code whose length differs the length for reset

At all other times, the limit remains at the minimum by default, making bypassing the protection by simply stopping the process more difficult, which is how this differs from the standard Duress approach, which is why it is called Ultimate, meaning ultimate protection

Length for reset can be not only longer, but also shorter than your password length, because data will be wiped precisely after submitting the code, not right after its input

For data deletion, it is sufficient that a code of such length differs from your password

Since the reset trigger is length, the app does not require characters display
