I’ve done this before as well. It truly baffled me because of how much in undermined me sense of being totally aware of my body. I truly believed I was hitting the right keys (I know how to type after all) and I never noticed any issue when writing normally, but only when typing my password. But of course I couldn’t see my password as I typed, while in other cases I would subconsciously correct any resulting typos because I could see them. I had no reason to classify typos due to standing as any different than the regular errors I might make while typing.
Almost felt like a bug in error correction loop in my brain, or maybe more like an unconsidered edge case.
I somes subconsciously correct typos even when not looking at them. It drives me crazy when UI design breaks this, like fixed-length security code / PIN entry UIs that automatically submit when you enter the last character of the code.
I also tend to memorize long (8+ digit) PINs based on the physical layout of the keys, so if I need to enter a PIN set up on a phone-style keypad on a normal keyboard or numeric keypad, or vice versa, I need to visualize entering the PIN on the original input device to remember it.
