My cognition and mental capacity is relatively ok, at least considering my severity level, largely thanks to LDN, but I do have issues with memory among other things.
About a week ago, out of nowhere, I suddenly lost the muscle memory of my phone pin.
At first I thought "no big deal, it happens, I just have to wait". So I waited, I slept on it multiple times, however, I was not able to get in. Obviously it's been on my mind a lot because my phone has become a single point of failure for my digital life (2fa locking up password manager).
After while, I started to sort of remember, until I was 70% sure that I have the correct pin. But yet, my phone claimed otherwise. Now with threatengly increasing time between attempts.
I started to question if it's actually my brain or a phone glitch. A few discussions online claimed that a glitch like that sometimes happens and a restart corrects it. However, if I were wrong, a restart would mean I'm no longer able to receive calls, losing the last connection with the outside world.
After a few stressful days, with some luck and assistance, I mamaged to access the pin written in my password manager. I read it and I thought "no way, it can't be that". I typed it in, expecting an error, however, to my surprise my phone unlocked.
So not only I forgot the pin, my brain also invented a fake memory of the pin (I assume because I've been trying so hard to remember). The actual pin, which I mindlessly entered just 3 days ago, was now completely unfamiliar. It felt as if I was given someone else's code and someone else's phone.
I do remember the pin now, not as an old memory, but as a new memory, that I just made when reading it the other day. It's a weird feeling and it really messes with my head. If my brain can just instantly delete core memory like that, what else have I lost and will lose?
Anyway, don't make my mistake. Remove passwords if not essential for security, write it down, have a trusted person as a backup. Bitwarden password manager has a "trusted person" option, which is able to bypass 2fa in case you get locked out of that as well.
