About

This extension provides unlinkable cryptographic tokens for websites that support the Privacy Pass protocol. For example, these tokens can be used on Cloudflare-protected websites to improve your human signal.

How it works?

Privacy Pass Providers: Cloudflare Research

Get tokens
1. If a website requests a Privacy Pass token, the extension is automatically going to request you to perform the associated challenge.
2. One page will open with a challenge to be solved.
3. Solve successfully the challenge and the extension will get **one** token.
