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 my go-to authenticator! The browser extension makes this really easy to use, and syncing with Google and backing up to Google Drive lets me use this across my devices. Really zero complaints, other than I wish I could add custom icons... but that's sooo minor!

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!
