Only for mac os btw

macos only, use linux

macOS only!... on the description does not mention anything about this!

"This extension is a companion app and works exclusively with our macOS* application. It seems you’re not using a macOS* device, so this extension isn’t supported on your platform right now."

Authenticator App is a great extension that makes keeping track of authentication codes easy and synced with my other devices. I prefer this over using Proton Pass to manage 2FA so that there is a wall of separation should one be compromised. Highly recommended for reliability and ease of use.

Not yet available for FIrefox. Unsure why they even uploaded the app, so I can download it, just for it to tell me it's not yet available on this platform...
