スーパーセキュリティ パスワード管理

Trust Factors: This extension has several concerning trust indicators. With only 10,000 users and a very poor rating of 2.0 stars from just 4 reviews, it lacks widespread adoption and user confidence. The Japanese name suggests it's a password manager ("Super Security Password Management"), but the extremely low rating raises serious questions about its reliability and functionality. The absence of clear developer information further diminishes trustworthiness.

Concerns: The permission combination is extremely problematic for a password manager. The webNavigation permission allows comprehensive tracking of your browsing behavior across all websites, while the all_urls permission grants access to every website you visit and their content. The nativeMessaging permission enables communication with local applications, which could potentially be exploited. For a password manager, these permissions seem excessive and create significant privacy and security risks. The use of Manifest V2 also indicates outdated security standards.

Recommendations: Do not install this extension. The combination of broad permissions, poor user ratings, lack of developer transparency, and low adoption makes it unsuitable for managing sensitive password data. If you need a password manager, choose well-established alternatives like Bitwarden, 1Password, or LastPass that have proven track records, transparent development teams, and appropriate permission models. These established options provide better security without requiring such invasive permissions.
