What is a Browser User Agent?
A browser user agent is a short string of text that your browser sends to websites when you visit. It identifies details like your browser name, version, and operating system.
Example:
Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/118.0.0.0 Safari/537.36
This tells the website that you’re using Chrome on Windows 10.
