There isn't anything. It has always worked flawlessly and has never failed. Changing devices was a breeze. Review collected by and hosted on G2.com.

The ability to use two-factor authentication across multiple accounts, on multiple devices, including my laptop and mobile devices.

On iOS, it's also possible to add it to the Today screen, where it shows the current values if the phone's unlocked - this makes it even quicker and easier to log into things. Review collected by and hosted on G2.com.

The fact that, on the iOS Today screen, the current numbers across all accounts can briefly be seen if a user has previously used this screen in unlock mode but subsequently locked it. Whilst the view updates itself to its default locked state quite quickly, I'd still be happier if it didn't show anything by default. Review collected by and hosted on G2.com.

Authy is the best Two Factor Authentication (TFA) manager I've ever used. It has plugins for my desktop browsers, an app for my phone, and it even includes a widget for Android devices. Review collected by and hosted on G2.com.

It does not include a Windows phone app -- my work phone runs Windows, so I cannot use it for any of my work accounts. Review collected by and hosted on G2.com.
