Password security

Sorry that password has expired- you must register a new one.
Did anyone discover that password and hack my computer?
 No, but your password has expired- you must get a new one.
Why then do I need a new one as that one seems to be working pretty good?
 Well, you must get a new one as they automatically expire every 30 days.

Can I use the old one and just re-register it?
 No, you must get a new one.
I don't want a new one as that is one more thing for me to remember.
 Sorry, you must get a new one.
