CK-Authenticator G3

The extension has a substantial user base of 2 million users, which suggests some level of adoption. However, the extremely low rating of 1.1 out of 5 stars from 80 reviews is a major red flag indicating widespread user dissatisfaction or potential malicious behavior. The developer "packetkeeper.net" lacks clear company information or reputation indicators.

The extension exhibits multiple severe security risks that are disproportionate to what an authenticator should require. The combination of webRequest and webRequestBlocking permissions with all_urls host access creates a dangerous capability to intercept, modify, and block all web traffic. The identity permission adds another layer of concern by potentially exposing user identity information. The unsafe WebAssembly execution policy could hide malicious code. Most critically, these extensive permissions far exceed what a legitimate authenticator would need - authentic two-factor authentication tools typically require minimal permissions.

Do not install this extension. The combination of critical security risks, extremely poor user ratings, and excessive permissions strongly suggests malicious intent. If you need an authenticator, use established alternatives like Google Authenticator, Authy, or Microsoft Authenticator. If already installed, remove it immediately and scan your system for potential compromise. Consider changing passwords for any accounts accessed while this extension was active.
