All of a sudden (like within the span of 10 seconds), my iMac has stopped recognizing my password. Any time I try to enter it (to empty the trash, go into System Prefs, etc.), it tells me that it is invalid. I just used it a few minutes ago, and when I tried to enter it into System Prefs literally 10 seconds later, it locked me out. What's the problem with this? Any suggestions of how I can fix this?
