Does not work without giving away my phone number. OTP protocol does not actually require a phone number, and I would not want this app know both the sites I use, my usernames there, my password + OTP AND my phone number. Leaks away private data (observed through network firewall). Not really needed for functionality. Makes one wonder if the OTP credentials are stored somewhere too... You can never know, I guess...
Had to un install and re install and now I can't access my coin base cause authy is not allow my device, says it doesn't recognise my device and doesn't have an option to reset my infor through email.
This is a well-designed app that provides a very valuable service. It's a big time saver not to have to use multiple authenticator apps, or to rely on SMS codes. I'd love to see Android Wear support.
It's good and fulfills all its promises, nevertheless, other alternatives (like LastPass Authenticator) offer some extra features (push one-tap-login notifications) that Authy lacks. Please, add them to be on par.
The 2fa tokens are the keys to the kingdom these days. I suggest you commission a security audit to ensure users it's not just your word we have to give confidence on your code. As for suggestions, please add watch support and night theme.
Stupid slow recovery process for such an important app. Don't replace your phone if you use this for anything important folks..
