Changing Passwords

New passwords must meet the criteria described in "Password Requirements".

Changing Your Own Password

To change your password, type

station1% passwd

You will be prompted for your old password and then the new password and then the new password a second time to confirm it.

Changing Someone Else's Password

To change someone else' password, use:

To change another user's password in the same domain

passwd username

To change another user's password in a different domain

passwd -D domainname username

When using the passwd command in an NIS+ environment (see "The passwd Command and "NIS+ Environment"") to change someone else's password you must have modify rights to that user's entry in the passwd table (this usually means that you are a member of the group for the passwd table and the group has modify rights). You do not have to enter either the user's old password or your password. You will be prompted to enter the new password twice to make sure that they match. If they do not match, you will be prompted to enter them again.

Changing Root's Password

When changing root's password, you must always run chkey -p immediately after changing the password with the passwd command. Failure to run chkey -p after changing root's password will result in root being unable to properly log in.

To change a root password, follow these steps:

1. Log in as root.

2. Change root's password using passwd.

   Do not use nispasswd.

3. Run chkey -p.

   You must use the -p option.
