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.

The app has significantly improved its behavior over the last two years. If NFC is being iffy, the usb connection works wonders.

TLDR: APP FINE. PROBLEM IS THE YUBIKEY. The NFC function works fine on most devices; if not, get a USB adapter for a few bucks so you can plug it in. Problem is that my Yubikey filled up far too quickly.. maybe when they designed it, 25 slots seemed a lot, like 640K of memory once did in PC's. But in 2022, that's nothing. Now shopping for competitor devices with more slots. PS: Buy 2 devices, keep 2nd in safe as backup
