first-time i was worried it wouldn't work or i would lose my account due to the code not working when it asks for auth code. I connected it to a game and it worked! App is easy to use. When you connect a "Service" It gives you a randomized bunch of 6 numbers. refreshes every 30 seconds. While you have to put it in before it refreshes. I would rather prefer this way as it to me is more safe. So far i haven't gotten any problems with it. Even comes with a passcode to make sure it's you! 10/10!

Got annoyed with Authy when I realized I couldn't just install it on my new phone without accessing an account. I manage my own 2fa codes and don't need or want account sync. Found this app and it's exactly what I need. Blazing fast QR code scanner, pin code access, and optional backup sync. Looks great too! Much better UI than Authy.

Great App. Much better than similar other apps. I have few feedback - Can you make the account name in a different color (it is currently gray) as it is not very well readable. It is particularly useful if multiple accounts in same website and want to quickly identify the right 2FA. Secondly the browser extension is not perfect for multiple accounts on same website. Can this be improved? And lastly, please create desktop app.

Hi, thanks for the suggestions. I will ask about the colours, but for now, the badge colour can be changed to recognise different codes for the same service. Multiple codes for one service on BE should already be available (if not, this will be released in the near future). As for a standalone PC app, we have some plans for it ✌️
