A User Agent string is a unique identifier sent by your browser to every website you visit:

  • Identification: It tells the server if you are on a mobile device or desktop so it can serve the correct layout.
  • Compatibility: Developers use this string to troubleshoot bugs that only happen on specific browser versions.
  • Security: It helps in identifying bot traffic or suspicious login attempts from unknown devices.
Can I change my User Agent? +
Yes, many browsers allow "User Agent Switching" via Developer Tools. This is useful for testing how a site looks on an iPhone while you are on a Windows PC.
