If you were having such a challenge, it’s our hope that you have gained enough insights on the matter. In this tutorial, we have highlighted two commands that you can conveniently use to force a user to change their password.
When user jack tries to log in the next time, he will be required to change his password in the same manner as demonstrated in the first part of this guide. The syntaxes are provided below # chage -d 0 įor example, you can expire a user called jack as shown.
Also, you can use the –lastday flag that specifies the number of days since the epoch ( January 1, 1970) You can achieve this using the -d option followed by 0 which implies day zeo. You can also use the command to expire a user’s password and force them to change it on next logon. The user will be required to first provide the previously used password, then enter the new password and then confirm it as shown below.įorce user to change password using chage commandĪs we have previously, the chage command gives insights about the user’s aging information. On the next login attempt, the user bob will get a notification that their password has expired and should be changed before proceeding. # chage -l bobįrom the output, we can clearly observe that the password for user bob need’s to be changed on next logon. Thereafter, you can verify the password expiry or aging information by running the chage command as shown. While your computer is booting, from the boot menu select the 'recovery mode' option. The -e option (also expressed as –expire) simply expires the user account’s password and forces the user to change the password on the next logon.įor example, to retire bob’s password simply run the command # passwd -e bob This is possible using the syntax provided. You will be prompted to provide a new password for the user account and later confirm it as shown.Īside from setting or changing a user’s password, the passwd command can also be used to compel the user to change the password once they attempt to log in the next time. For instance, to reset the password of a user called bob, simply execute the command below as root user: # passwd bob
The passwd command is mostly used to assign or change a user’s password on a Linux system. Force user to change password using passwd command We have used Ubuntu 20.04 for demonstration. There are two ways of compelling a user to change the password at the next login. This ensures the safety of the user’s account. This ensures that they set a different password – and a strong one for that matter- to thwart any brute-force attempts by malicious users or hackers. Once you have created a new user on your Linux system, you may need to prompt them to change the password at the next login to comply with the password policy.
