Ratings and reviews

Got 2 one as a spare, waste of $s. Does not work on my phones, (Android - 13 OS),or Apple iPhone. When plugged into USB on Samsung ph, Keyboard disappears. Support say OS is the problem on Both phones¿. Any Free authenticator app, works on both so it's the 5ci key which is bad, NFC is not seen , on either Ph: Save your Time & Money: Support is a Joke; AVIOD, Use any of the Many free app for your Wallet instead:🚫🗑

A great, open-source authenticator from a company focused on security and privacy. This app is non-invasive (requiring minimal permissions, only Camera for QR codes and NFC). Made to work for the physical key and is all done on the device, It is simple and does its job as intended, with no unnecessary features or advertisements. Highly recommended for its transparency and simplicity.
