Overview

Product summary

Review the store description, core capabilities, and common use cases.

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.

Задумка возможно интересная, но оно не работает. Приходится часто нажимать одну и туже ссылку для перехода. Много раз перезагружаются страницы. В некоторых случаях это критично, например при игре в онлайн казино. Лучше уж один раз при входе разгадать каптчу, чем терять прогресс и доход из за обновления страницы.

Iwillpushyouoffacliff2021年6月23日

Live Orca Reaction2021年6月17日

IT NEVER WORKS, EVEN WITH THIS I HAVE TO CONSTANTLY DO THE CAPTCHA, THIS IS A WASTE OF YOUR TIME.

Privacy Pass anonymous token client that obtains unlinkable cryptographic tokens from attesters to present to websites supporting the PrivateToken protocol

Enables users to prove they are human to Cloudflare-protected websites without compromising privacy—avoids repeated CAPTCHAs and prevents tracking across sites through anonymous, unlinkable tokens

1. User visits a website that supports Privacy Pass and sends a PrivateToken WWW-Authenticate challenge header. 2. The extension detects the challenge and opens a new tab to the Cloudflare Turnstile attester. 3. User solves the attestation challenge (proves they are human). 4. The extension receives an anonymous cryptographic token from the attester. 5. The token is automatically included in subsequent requests to the website, proving the user is human without linking to their identity.

Target users: Privacy-conscious web users / Users frequently visiting Cloudflare-protected websites / Users who want to avoid repeated CAPTCHA challenges while preserving anonymity

Extension source is bundled/minified (background.js is 238KB single file), making deep logic analysis harder but key patterns are clear
Cannot fully verify if destination Cloudflare attester service requires login since it's external—however the extension itself does not

Monetization

No paid features detected

No payment, subscription, premium, upgrade, billing, or price references found in the source code. Grep for 'premium', 'payment', 'subscription', 'upgrade', 'billing', 'price' all returned 0 matches in background.js. The 'pro' keyword hits from the static scan are all false positives: Object.prototype methods (lines 2-21), Object.getOwnPropertyNames (line 19), and SERVICE_WORKER_MODE.PRODUCTION (line 633). The extension is fully functional without any gated features or payment flows.

Confidence: 95
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension implements the Privacy Pass anonymous authorization protocol. No user account, login UI, or credential entry exists anywhere in the codebase. Grep for 'login' and 'account' in background.js returned 0 matches. The 'auth' keyword hits are all cryptographic authentication (AES-CCM tags, WWW-Authenticate header parsing at lines 6340-6396), not user account authentication. The 'token' hits refer to anonymous Privacy Pass cryptographic tokens, not login/session tokens. The options page (options/index.html) only contains attester URL configuration and service worker mode selection—no login fields.
