just "passwd mechko" I think, if you're logged as root ? tried it ? as existing password use roots or mechko's (in this case roots)

Thanks a lot. I was looking at man pages even before I tried changing it so I got confused :-p – mechko Jan 10 '10 at 1:48
passwd $user as root doesn't require providing the current password. – Blacklight Shining Oct 7 '13 at 12:49

Old school, more powerful than necessary method:as root empty the password field for that user in /etc/passwd or /etc/shadow. Then you can login and change the password.

I'll keep that in mind for next time :D – mechko Jan 10 '10 at 1:49
no, don't, unless you know how to fix it when you break things. the passwd command exists for a reason. – user23307 Mar 1 '10 at 2:14
