- Authy is just the best yet. They have a beautiful user interface with icon support for multiple websites and a native app for Mac!
- I used to use Authy but I find it easier to get access to my 2FA code within 1Password, mainly because I use 1Password for my regular passwords. "1 app does it all". FYI: To use the 2FA feature in 1Password, set a field as "One-Time Password" and use the provided QR code reader if needed.
- Google Authenticator because Heroku recommended it and it works for everythingGoogle Authenticator is very usefull and can be used almost everywhere. However, the app lacks some features such as a search bar, an interface too simple and for exemple I really think that adding website icons and a categorisation system can be very cool. Despite this, I use it since 2-3 years and it works absolutely perfectly fine !
- It's the latest free TOTP Authenticator with premium features which are not provided as one in many of the other apps like:- Code generation, Widget Support, Multi-Account Support, Completely Offline, Extra Security, Account Customisations, Cross platform Backup/Restore, Multi-Device support and much more.
