YubiOTP in demo app - "Cancelled by user" when reading over NFC #40

Closed mattdsteele closed 2 years ago

I'm new to NFC Yubikeys, but I'm looking to read an OTP via NFC, with a Yubikey 5, on a device with NFC enabled running Android 8.1.0.

After installing the demo app, I can see on the Device Configuration screen that OTP is enabled on both NFC and USB. When connected via USB, I can also short-tap to generate an OTP, via the standard HID approach.

However, when trying to read an OTP via NFC however, I constantly see a "Cancelled by user" toast on the YubiOTP page. This makes it appear that the result that's coming back is null.

Any suggestions on how to debug this?

We were able to resolve this; OTP through NFC was not enabled on the Yubikey.
