Comment: People do forget ALL the time (Score 2) 1009
Surely forgetting your password is perfectly legitimate.
Ask any first line corporate helpdesk staff member what the most common problem is, and I bet it's users forgetting their passwords and locking themselves out. Virtually every website has a link to automate the reset process. People forget their passwords all the time.
OK, I accept it's less likely that you'll forget the password to access your home PC, but I've done that, been there, had to reboot from a recovery disk - if the data was encrypted I'd have lost access to it.
