Coming from Authy to test the water with a new 2FA app, I'm a bit disappointed that there's no grid view like Authy or a compact view with 2 columns. The current compact view doesn't improve much from list view and you still have to scroll to find a token or use search type name, which takes extra time when you have a lot of accounts. Also unlike Authy, you can't add logos for less known brands, either you keep a generic logo or have to make a request to their team everytime..

Thanks for the feedback, and we're sorry to hear about the negative first impression. As for the services, creating groups of codes is always possible. That way, you won't have to scroll through all of them only click on the correct group.

Probably the best TOTP app I've tried, but still not perfect. Plus: Can be protected by PIN or biometrics. Entries can be organized in categories, sorted and searched. Entries can be renamed and assigned custom icons. Minus: QR code scanner is very slow. Can't automatically grab favicon and use it as a custom icon. Can't export individual entries.

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
