Applying the passwd command
The passwd command allows the user to create or change a password. This feature is also helpful if there are multiple users and security is a concern. There is a functionality called password expiration. This will also work great for temporary users or contractual employees. This functionality will require the user to renew or change the password after a preset amount of time. Temporary user accounts can also be set with actual user expiration.
For Red Hat-based Linux system, again use the userconf command (as root), such as this: # userconf &
Navigate to the User dialog box, and click on the Params tab.
Use this tab to indicate the number of days before password must be modified, how long a user account is good for, when the warnings of impending expirations are going to show up, and the amount of time an account or password is good after a warning has been issued.
SuSE Linux administrators can turn to the yast command’s user dialog box. But you must press the F6 key when inputting the user’s name.
Use this dialog box in the same way as you would operate userconf’s controls. When you are done, use the Tab key to highlight the Continue button in order to return to user configuration.
