How To Force User To Change Password in First Login

Here come to my attention when i want to automatically have my new linux/unix users to change the password when they login into the server.

Login into your server with root access

type chage command :
#chage -d 0 <username>

example i have a username : fahmi

#chage -d 0 fahmi

-d mean : we will force user to change password when they login into the server for the first time
