Changing Your Password

To maintain security, you should change your password regularly. (See "Choosing a Password" for password requirements and criteria.)

Note -

The passwd command now performs all functions previously performed by nispasswd. For operations specific to an NIS+ name space, use passwd -r nisplus.

Changing your password is a four-step process:

  1. Run the passwd command at a system prompt.

  2. Type your old password at the Enter login password (or similar) prompt.

    Your keystrokes are not shown on your screen.

    • If you receive a Sorry: less than N days since the last change message, it means that your old password has not been in use long enough and you will not be allowed to change it at this time. You are returned to your system prompt. Consult your system administrator to find out the minimum number of days a password must be in use before it can be changed.

    • If you receive a You may not change this password message, it means that your network administrator has blocked any change.

  3. Type your new password at the Enter new password prompt.

    Your keystrokes are not shown on your screen.

    At this point the system checks to make sure that your new password meets the requirements:

    • If it does meet the requirements, you are asked to enter it again.

    • If your new password does not meet the system requirements, a message is displayed informing you of the problem. You must then enter a new password that does meet the requirements.

    See "Password Requirements" for the requirements a password must meet.

  4. Type your new password again at the Re-enter new password prompt.

    Your keystrokes are not shown on your screen.

    If your second entry of the new password is not identical to your first entry, you are prompted to repeat the process.

    Note -

    When changing root's password, you must always run chkey -p immediately after changing the password. (See "Changing Root Keys From Root" and "Changing Root Keys From Another Machine" for information on using chkey -p to change root's keys.) Failure to run chkey -p after changing root's password will result in root being unable to properly log in.

Password Change Failures

Some systems limit either the number of failed attempts you can make in changing your password or the total amount of time you can take to make a successful change. (These limits are implemented to prevent someone else from changing your password by guessing your current password.)

If you (or someone posing as you) fails to successfully log in or change your password within the specified number of tries or time limit, you will get a Too many failures - try later or Too many tries: try again later message. You will not be allowed to make any more attempts until a certain amount of time has passed. (That amount of time is set by your administrator.)
