You need to use the passwd command to changes the user’s password.
Rules for changing passwords for user accounts
- A normal user may only change the password for his/her own account.
- The superuser (root user) may change the password for any account or specific account.
- The passwd command also changes the account or associated password validity period.
First, login as the root user. Use sudo -s or su - command to login as root. To change password of specific user account, use the following syntax:
passwd userNameHere |
To change the password for user called vivek, enter:
# passwd vivek
Sample outputs:
To see password status of any user account, enter:
# passwd -S userNameHere
# passwd -S vivek
Sample outputs:
vivek P 05/05/2012 0 99999 7 -1
The status information consists of 7 fields as follows:
- vivek : Account login name (username)
- P : This field indicates if the user account has a locked password (L), has no password (NP), or has a usable password (P)
- 05/05/2012 : Date of the last password change.
- 0 : Password expiry minimum age
- 99999 : Password expiry maximum age.
- 7 : Password expiry warning period.
- -1 : Inactivity period for the password (see chage command for more information).
To get more info about password aging for a specific user called vivek, enter:
# chage -l vivek
