How to Use Passwd to Modify a User Password

Learning the basic commands computers use for operational purposes is a great way to save yourself a lot of frustration. Learning basic commands, such as how to use passwd to modify a user password, will save you time and hassle, because you can correct many issues yourself rather than calling for technical support.

Use Passwd to Modify User Password

Step1 Log on to your computer and network.

Step2 Type in passwd.

Step3 Use the passwd command to change your password information or your username.

Step4 Know that if your protocols specify a system password, this command may not be used to modify your password, and you will need to contact your IT department.

Use Passwd Options to Modify User Information

Step1 Learn the passwd options that might be useful to you. Please pay close attention to where lower case and capital letters are used, as the commands are case sensitive.

Step2 Use -a to add another user. The -a command should be used each time an individual is added to a password file.

Step3 Use -x to suspend a user. This command disables access for that user, who will no longer be able to modify files.

Step4 Use -X to completely delete a user. The entry for the specified user will be deleted from the files. Note that this command uses a capital X rather than a lower-case x.

Step5 Use -r user to enable a pserver to access the files. This command basically makes the pserver function as a virtual user for the files.

Step6 Avoid the use of the -D Domain command option. This command reduces the security of your system. It removes the need for a separate password. If you use the -D domain command then a general domain password of the user will access the files. This basically strips away a layer of security from your files and is not recommended.

Think About File Safety When Modifying Your User Password

Step1 Do not share your user password with anyone. Resist the temptation to share your password with anyone else, even someone you work with on a regular basis.

Step2 Choose a password that is easy for you to remember but hard for someone else to guess. Remember that any modifications made under your password will be assumed to be made by you.

Step3 Follow your company's directions regarding password length. Use the appropriate number of characters and alpha numeric combinations.
