Ratings and reviews

Feels much more secure than other apps after testing it out on a few accounts: 1. Does not collect any user data (this should be gold standard since the OTP generating algorithm works even without internet connection) 2. Locks you out of the app once you switch apps, requiring you to log back in using pin / biometrics 3. Ability to hide all other accounts' codes and only reveal the one tapped 4. Allows to import codes from other auth apps and sync with gdrive as backup

It's easy to set up, intuitive, and has always worked when I needed it. Also, not swimming in ads, which is a huge plus. I also just replaced my phone, and was worried about getting this set up on my new device. Turns out the tokens were backed up on Google Drive, so as soon as I installed this, BAM! Everything was there, already working. I couldn't be happier!

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!
