I find this quite weird. OK, my password are meaningless sequences of random characters, so maybe it makes things different; but I don't remember passwords as strings, I remember them as gestures. For most passwords I would have to imagine myself typing them to reconstitute their written or spoken form (which can sometimes be tricky if you have to enter them on an unfamiliar device or using an unfamiliar layout).

So I'm confused why after a few days you would still remember what the password means when you type it in.
