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.

I LOVE this APP! It's one of the most practical and functional apps I've ever used. I love the ability to color code the icons for work, personal, and other categories. I love the list feature and the ability to sort my keys. I also really like the encrypted backup feature that will allow me to recover my keys quicker if I end up in another gotta get a new phone ordeal! ❤️
