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!

The design is clean and modern and the app runs very smooth. It's also easy to use. I switched from Google Authenticator because I was having serious lagging issues and crashes. Backing up my codes in an encrypted, hidden, and password protected file on Google Drive is genius. I never have to worry about my phone being lost, stolen, or decommissioned. I would highly recommend this app.

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.
