I mean like, after I type a password on a computer, I’d rub my fingers across the entire keyboard to make sure any fingerprints/oil-residues gets evenly distributed so its harder to know the password. Same with phone unlock codes, I just use my fingers to rub against the part of the screen where the virtual keyboard was displayed.
Am I being weird? I’ve had this habit since the first time I got my first digital electronics.
Typing a password: keepass. I’m not typing my who knows how long passwords on my keyboard.
PIN Pad: I wipe it, and cover the pin pad too in case someone with good visual memory sees it.
ATM: metal pads don’t blatantly show on thermal imaging, so just cover it with my hands. Also try to shake off the card reader/metal pads, they’re built to resist that so if you manage to pop something off, congratulations you exposed a card skimmer.
Phone password: 32 character passcode, no Touch ID, good luck trying to get into it. If anyone can decipher it just by looking at the screen, at that point they deserve it.
