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.

For everyone's information, you have to plug the key into your port to scan the QR code initially, as to the NFC it is a question as too how much garbage you have installed on your phone ,how old that phone is,and if you initially plugged the key in and scanned from your phone.If there are backup codes, you better keep them in a printed safe place. Have another key for backup, scan the codes to that key when doing the primary key from a computer. all phones are not equal,they behave different.

Don't upgrade. It still does exactly what it claims but the previous version was leaps and bounds better. The accessibility of this version has jumped ship - the dark mode is grey, not black and the codes are half the size which may cause problems for visually impaired people. There are far fewer settings, many I use. I'd hoped this version would bring the ability to sort accounts but you can still favourite some which helps. I'm rolling back to version 2.2 if I can. This is a backwards step.
