For my most sensitive passwords, I select the “Master password re-prompt” option to ensure that nobody can view them using an already logged-in session.
On PC, this is not a problem since I have a keyboard and re-typing my master password is quick and easy.
On mobile (specifically iOS), this makes viewing the password very tedious since I need to re-type the master password using the iOS keyboard.
I would like to use Face ID to conveniently unlock these passwords instead of re-typing my master password. Without this, the “Master password re-prompt” feature is almost too annoying to use.
