Guest

A guest is an anonymous user account that provides access to a computer on a limited or temporary basis. Although some computer operating systems have guest accounts by default, most have to be set up manually by the computer's administrator.

Unless you plan on having unauthorized users on your computer or network, we recommend the guest accounts be disabled to prevent any potential security risks. This account or username is commonly one of the first accounts a potential hacker may try if they can't access a higher one.
