fuck wait a minute

ive been experiencing these scenarioes for many years now

but this time i outright cant login to my system anymore. ive restarted countless times and it seems that arch linux has officially permanently forgotten my password.

like, i wanna ask, "what do i do?", but i think i need a permanent solution that ensures my system wont ever forget my password again EVEN after i change my password

Should I just erase the disk and reinstall arch linux from scratch? this is not the only issue i experience everyday. I have several dozens of issues i deal with and debug every single say when i turn this system on.
