With a Mozilla account, you can have your two-factor authentication synced across all your devices using Firefox. It works perfectly. Looking forward to the mobile version!

Отличный аутентификатор. Полная альтернатива смартфону. Пользуюсь больше года.

It works great on Firefox desktop, I just wish it was also available for Firefox Android.

Works awesome!

Its an awesome Authenticator generates add-on

It works. To scan, you have to click and drag a box around the qr code

I'm so glad that I downloaded this extension. I use it constantly and it saves me a TON of time. Now I use 2FA for every single account and don't have to find my phone every single time. VERY HIGHLY RECOMMEND.
