Change the Password in UNIX

How do I change the password in UNIX?

To modify a user's password or your own password in UNIX use the passwd command. Open the terminal and then type the passwd command entering the new password, the characters entered do not display on screen, in order to avoid the password being seen by a passer-by. The passwd command prompts for the new password twice in order to detect any typing errors. The encrypted password is stored in /etc/shadow file.
