My 93 year old father has not been able to login on his iMac running OS 10.4 the past 3 days. I have entered his Apple password, email password, and every password he's used this past year. Nothing has worked including his Secret Question. Any advice on how I can help him login to his computer.
iOS 4.3

You may wish to set up a separate administrator account for yourself to act as a backdoor should this happen again or should he forget his password. It is very easy to reset passwords when you have an admin. account.
