The system administrator also establishes an initial password. However, users are expected to change their password immediately after logging in the first time . 1.3. Pick your new password then enter the command to change your password: passwd . When you enter the command the system will prompt you to enter your current password, which must be entered correctly before it allows you to change it. Next, it asks you to enter your new password, then it asks you to enter the new password a second time to make sure you did not accidentally type something wrong the first time. If the second entry matches the first one, your password will be changed and the system will display a message to that effect. You will need to remember the new password to log in the next time, so be sure to write it down somewhere you, but no-one else, can find it in case you forget it....
