Is it because your password is too simple? Just a thought :) – Meer Borg May 22 '13 at 15:33
i used numeric,alphapets and special characters too in my password and it's length is 12 is it simple? – Nagarajan anbazhagan May 22 '13 at 15:35
Maybe it checks small passages in the password and it contains your user name or simple passages that are forbidden. Does it work with other passwords? – verpfeilt May 22 '13 at 16:16
@chocobai i checked everything but it's not working :( – Nagarajan anbazhagan May 22 '13 at 16:23
I think the setuid bit has to be set on passwd or something, maybe this went somehow wrong? This is how my ls-lh looks like on passwd: -rwsr-xr-x 1 root root 46K Apr 18 03:28 passwd About setuid bit: I think the fourth character should be the setuid bit... or something :D – verpfeilt May 22 '13 at 16:30

It might be because you filesystem is mounted with read-write permissions(are you in Recovery mode?).

To mount your filesystem in read-write mode, in the terminal type:

sudo mount -o rw,remount /

and then change your password using passwd <username>.

Have you tried:

Going to System Settings>User Account

  • Under Login Options:
  • Clicking where it shows bullets next to password
  • Follow the directions in the new window

I tried that too but I can change my new password from the generated password but I can't change it to what I want. @AnythinkM3tal – Nagarajan anbazhagan Jul 14 '13 at 15:26
