What is User Agent (UA)?

In computing, a user agent is software that acts on behalf of a user. A common use of the term refers to a web browser that tells a website information about the browser and operating system.

That's according to wikipedia, and I can simply understand that when logging into Facebook with Chrome browser, Facebook will receive information that there is a computer using Chrome browser logging into their page, Facebook knows that information through user agent

The tool's fake UA function allows us to trick Facebook into thinking that we are accessing the page on another browser (eg safari, opera,..) using another device (eg Nokia, Iphone,...)

Fake user agent can reduce checkpoint rate when you use a large number of accounts on 1 computer, you just need to choose a user agent and paste it into the txt file in the tool and the tool will fake it for you.
