Change Your Password

You can make your Mac and your shared folders more secure by changing your password. For example, if you turn on file sharing as described in the next section, you can configure each shared folder so that only someone who knows your user account password can get full access to the data in that shared folder. Similarly, you should change your password if other network users know your current password and you no longer want those users to have access to your shared folders. Finally, you should also change your password if you feel that your current password is not secure enough. See the Tip to learn how to create a secure password.
