Frequently Asked Questions

What is a user agent string?

A user agent string is a line of text that your browser sends to websites you visit. It contains information about your browser type, operating system, and sometimes other details like the browser version and rendering engine.


What is my user agent string?

Your user agent string is unique to your browser and system. To find your current user agent string, you can search for “what’s my user agent” in a search engine or use online tools specifically designed to display your user agent.


What is my default user agent string?

Your default user agent string is the user agent that your browser is set to use by default, without any modifications. This typically includes details like the browser name, version, operating system, and the rendering engine.


Can I change my user agent?

Yes, you can change your user agent string. Many browsers offer extensions or developer tools that allow you to modify the user agent. This can be useful for testing how a website behaves on different browsers or devices.


What are some other user agent strings?

Other user agent strings vary depending on the browser, operating system, and device. Here are a few examples:

  • Google Chrome on Windows 10:
    Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/91.0.4472.124 Safari/537.36
  • Mozilla Firefox on macOS:
    Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:89.0) Gecko/20100101 Firefox/89.0
  • Safari on iPhone:
    Mozilla/5.0 (iPhone; CPU iPhone OS 14_6 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/14.0 Mobile/15E148 Safari/604.1


If I change my user agent, can sites still detect my browser?

Even if you change your user agent string, some websites can still detect your browser using other methods. These include analyzing the way your browser renders content, JavaScript capabilities, or using browser fingerprinting techniques. While changing your user agent can mask some information, it’s not foolproof against all detection methods.


Why would someone want to change their user agent?

People change their user agent strings for various reasons, including:

  • Testing: Web developers test how their websites perform across different browsers and devices.
  • Privacy: Some users change their user agent to reduce tracking by websites.
  • Accessing Content: Occasionally, websites restrict content based on the detected browser or device, so users might change their user agent to bypass these restrictions.
