What Is Browser Fingerprinting?
This collection of device characteristics is sometimes referred to as a browser fingerprint. Unlike cookies, which store data locally on the user's device, fingerprinting relies on technical signals that are difficult for users to modify.
In some cases, browser fingerprints can uniquely identify a device among millions of users. This allows websites and advertising networks to track visitors across multiple websites even if cookies are disabled.
Why This Matters
- Advertisers build profiles without consent
- Malicious actors can identify targets for attacks
- Price discrimination — some sites show different prices based on device
- No opt-out — fingerprinting works without cookies
How to Reduce Your Fingerprint
- Use privacy-focused browsers — Firefox, Brave, Tor
- Enable tracking protection — built into most modern browsers
- Use a VPN — masks your IP address and location
- Install privacy extensions — uBlock Origin, Privacy Badger
- Limit JavaScript — blocks most fingerprinting scripts
