## Review summary

Authenticator App is praised for its ease of use, reliability, and effective syncing of authentication codes across devices, providing secure 2FA management. However, multiple users highlight that the extension is exclusively compatible with macOS, causing issues for users on Linux or unsupported platforms. Additionally, the Firefox add-on's description lacks clear information about these platform restrictions, leading to confusion. Overall, while it functions well for macOS users, its limited platform availability and unclear communication are significant drawbacks.
