Can any od these scenarios happen theoretically the current way it's coded. Either through some app bug or other situation.
Durrss pw is set to 123456 just for illustration.

A) bitwarden asks for pw, i enter pw Xyz123456@
Can this possibly trigger duress?

B) BFU pw someone enters XyZ123456#
Will this trigger duress?

C) fingerprint +2nd factor
Someone access fingerprint but enters pw
0123456
Will this trigger duress?

D) Typing a 123456 in Vanadium at any page or setting screen. Can this trigger duress or it is just impossible.

E) Dialing a person with phone number 010-1234567
Can dialer possibly trigger duress?

F) Using a banking app or Aegis, with pw 123456 or 012345678 can this trigger duress?

G) Any app which is setup to unlock with fingerprint, will it unlock with fingerprint +2nd factor or only finger. And if 2nd factor types 0123456 will it trigger duress?

I want to know if there is technical possibility that i could trigger duress not by purpose basically

    JayJay The duress password/PIN has to be entered into a device unlock credential prompt. The most obvious device unlock credential prompt is the profile's lockscreen.

    As an example, assuming that your duress is set to 123456 – then on the lockscreen, you have to enter exactly 123456 and then confirm the input with the confirm button as you always do when unlocking your profile (unless you have set the lockscreen to auto-confirm). Entering 1234567 won't trigger duress.

    If an app triggers an OS device unlock credential screen, then entering your duress password/PIN into that screen and confirming the input will trigger duress. For instance, if you set Vanadium to lock incognito tabs when you leave Vanadium, the unlock screen that Vanadium displays to you is a device unlock credential screen – if you enter your duress password/PIN there, it will trigger duress. Try enabling that setting in Vanadium and you'll see how the prompt looks.
