Is there any way to access a user's password given the name of the user?

Why would you want to do that? It's a bit of a security issue...

Also, once you access the password, how would you decrypt it

You can't, that's the point ;-)

(I would like to email the password to a user who has forgotten his)?

You should change their password and email them that new one. cheers, Chris
