Works and that's all I need, sent 2 QR code images from Google authenticator on my phone to my computer and it was done in an instant (2 mins). For those who don't know how to use this, why not just watch a Youtube tutorial? I mean why would you get an extension for 2FA when you don't even know how it works and how to use it yet? I think the UI is clean and is user-friendly with its icons.
