Over the last 10 days, I've been unable to log into my Airbnb account without receiving a pop-up saying "We don't recognize this device" and demanding a code (subsequently auto-sent to me via e-mail, Facebook, etc.) before I can proceed. As has been the case for the last 18 months, I'm using Safari and Chrome on a desktop Mac. There's never a follow-up prompt asking if I want Airbnb to remember this device. All of which was no problem the first few times, but now it's occurred countless times and is getting a bit aggravating. Any tips for a resolution would be greatly appreciated.
