Ratings and reviews

Except for one glaring deficiency, I really like it. The problem is with the UI ... I can't figure out how to replace an entry. (... or delete it so I can add the new one back in.) It's such an obvious use case, it couldn't have been missed in development, so I figure I must just not be seeing it in the UI.

This works great. It initially threw me because saved credentials only show up when you tap the key with your phone. They really need better documentation of how to use this- I think people are marking it down because they are confused about how this is supposed to work. I think it's pretty cool though.

I got completely confused by the UI in this update. You can still get your hardware key via NFC, but the app itself does you no favors in explaining how or giving visual feedback on when it does it. You have to change the settings under "On YubiKey NFC tap" from "Launch Yubico Authenticator" to "Copy OTP to clipboard" or "Launch app and copy OTP". It copies to the clipboard while providing no visuals. Seeing "No accounts" is confusing. This is operation is not OTP, that's misleading.
