I import my QR code, it says it worked correctly and it starts showing me random codes that aren't the ones on my phone and don't work

It was not so easy to use. There is a button that looks like it helps to scan a QR code, but it does nothing. So I clicked on the pencil icon, then imported the QR code, and it worked, but the extension only mentioned that some QR codes would work. The one that I use, a very popular one, was not mentioned. However, I tried and it is showing the proper codes now.

Sadly it does not work with some major authenticators (eg microsoft).
When it works it's nice - tried it with Octa.
When it does not work it's very confusing, as it won't give you an indication of what's happening. The interface is very basic, can't really tell what's what, how to start. Weird icons instead of simple textual buttons is a rubbish modern fad.

This add-on has been a godsend for me setting up 2FA on various sites. Unfortunately as of today the "Scan QR Code" button is doing nothing, and I can't add additional sites to the authenticator app. Not sure why this is failing at the moment. It would be great if the developer could look at this issue.

I'm so glad that I downloaded this extension. I use it constantly and it saves me a TON of time. Now I use 2FA for every single account and don't have to find my phone every single time. VERY HIGHLY RECOMMEND.

Good. No issue at all.

i have no idea how to use this app, how to open, how to add an account, on a PC
