Ratings and reviews

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!

Easy enough to use. I don't necessarily need biometrics or a pin to access the codes though because I already have to do biometrics or type in pins for the app I'm signing into with 2FA and a password manager, and it's a little frustrating to switch between them. It would be nice to have the option to enable them when editing any of the settings. Unfortunately, it's an all or nothing affair. Edit: I mean disable them for getting the one time codes, but enabled to access the service keys.
