Are QR codes for new client setup one time use or can they get reused by an attacker if found?
I setup 1P on a workstation without a webcam using a QR Code that I screenshot on my phone and emailed to the workstation (and deleted it afterwards but can you really trust it's not stuck in some cache somewhere?). Is this a security risk? Can an attacker find this QR code and reuse it? Or does 1P do the right thing and make them one use? Took a quick look in the white paper but didn't find anything.
