Okay, so this is on my laptop, which had the code for only a few minutes before syncing and disappearing. But anyway, my PC is completely unable to access the two-factor authentification and any of the backup codes, nor login, so I'm using my laptop. I got this PC late last year, and while originally keeping the codes, it no longer has them. Every time i search for solutions and such, I'm met at a dead end. Please help me. I don't know what to do.
