If you don’t have a password associated with your user account, anyone can access your files. A password controls who has access to your files. When you create a password, enter one that is easy for you to remember, yet difficult for others to guess. Good passwords are typically at least seven characters and include letters (uppercase and lowercase), numbers, and symbols. Once you create a password, you can always change it.

Security Alert: Working Smarter as the Administrator
If you are an administrator, it’s recommended that you log out and use another account for general work to avoid harmful damage to your computer by a virus or malicious user. For example, if a hacker received access to your computer with administrator privileges, the attacker could reformat your hard drive, delete files, or create a new administrator account.
