When you are designing a change in a password for a different account you will have to type in the password command and entailing it should be the username of the account needing password changes. If we consider a password change in the account named lineux then the command followed will be,

How can a user be pressured to change password at next login?
It has been set by default in many applications that the password set by a user for login details does not ever expire. Now a user can be pressurized to change the password when logging in for another time by undergoing a few commands while on the portal for Linux. The command that is provided for expiration of the old password is entailed by the name of the user:
$ sudo password --expire linuxize
Once you squeeze in the command mentioned above you will find the already existing password turning out to be immediately expired.
This procedure of immediate expiration of user’s earlier or old password will put pressure on the user to finally have the user password changed because of a message that will pop up when they log in again:
$ ssh firstname.lastname@example.org
OUTPUT WARNING: Your password has expired. You must change your password now and login again! Changing password for linuxize. (Current) UNIX password: Enter new UNIX password: Retype new UNIX password: password: password updated successfully Connection to 192.168.121.209 closed.
