Frequently asked questions
Can websites identify my browser from user agent?
Yes. The user agent usually shows browser, OS, and device type. It does not include personal info like your name or email.
Can I change my user agent?
Yes. Most browsers let you override it through developer tools or extensions. This is often used for testing.
Is user agent enough for tracking?
Not by itself. Tracking usually combines user agent with cookies and other browser signals.
Why do websites care about user agent?
It helps them show compatible content, fix layout issues, and decide which features to load for your device.
