Ratings and reviews

For a long time I was trying to figure out how to get my NFC key to work with my phone. I'd tap it and it'd ask which browser to use and then would open an unhelpful web page. Finally, I discovered this app and thought it might be the solution to using NFC on mobile. Nope! Tap is detected but nothing happens. Finally after a few taps it gives "Error in Yubikey communication". Sigh.

product works great except on Android while the Key works great as a physical authenticator, the application for Android seems to struggle with anything other then a passkey. the authenticator keeps coming up with an error in a small black box just off the bottom of the screen, sadly this results in not being able to add authentication via the provided QR Code. i have tested this on 3 different Android devices, two Samsung's and cmf

Very useful as it is! One function that's missing from the desktop version that I'd appreciate, the ability to program what the two OTP slots do.
