Ratings and reviews

Beeps loudly when security key is tapped, but is otherwise excellent. If there was a way to silence the beep, it would be prefect.

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.

Trying to delete it and I lost my key. Its not even registered right and my accounts got hacked
