# Browser Fingerprint:User Agent

The User Agent is a browser's native short string. By reading the user agent string, the website can identify the version of your browser and operating system.

Here is an example of a user agent value

Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/62.0.2785.8Safari/537.36

In this example, the site will assume that the user is using Windows 8.1 and Chrome 62. "NT 6.3" is a different release of Windows. You can view other released versions at Wikipedia article.

When creating the browser profile, following your selection of operating system filters on the overview page, the user agent values are retrieved from the Migratory Bird Browser fingerprint database. You can view the user agent value of the browser configuration file on the navigation bar.
