I work in IT and frequently see a lot ofI have observed many people who cannot remember their iPhone passwords or keyboardcomputer passwords off the top of their head. However, but if presented with a keyboard or ana phone with a functioning keypad, they can instantly remember exactly what their password or passcode is.
I'm curious to know what this kind of memory is called. Since it's somewhat related to visuals, but not necessarily (you don't need to look at your keyboard to type out your password.)
