Sounds like all you need is a copy of the Trusona app to spoof it.

The way I understand Trusona works is...

You are presented with a Trusona login ie QR code graphic that it also sends to the Trusona server.
Scan the QR code with the Trusona app on your phone.
The app compares the QR code with the Trusona Server.
Shows you are logged in on the phone, and logs in on the login.

So guessing the app needed login and the phone app have unique identifiers that check each other, pass the one time code and log you in.

Just trying to figure out what makes Trusona different that 2FA where you are texted a code you enter in the login.

On a side note, my bank stopped letting me do bill pay from Safari this morning. Reports cookies blocked and they work for other things on the site.
