I have it and I'm terrible with faces. If I spend long enough I can sort of pattern match distinct features but a whole face is generally lost on me.
Movies where you see a character that has aged or changed style are a mystery. My wife has to call out if it’s the same person. She’s pretty good at knowing when I’d have lost track.
I have aphantasia and I can remember faces quite happily but I can't visualise them when thinking about the person. Same as I can recognise a tomato, a ship, a train, whatever, but I can't visualise them in my mind.
