2FA using a postcard!


Upon joining the hyper-local social network "Nextdoor" - users are asked to verify their postal address. One option they offer is to have them send you a card in the post. So, I signed up, entered my address, and waited. A few days later, this popped through my letterbox. A few random thoughts... ✅ This is a nifty way to lightly verify someone's address!

User Safety at Product Hunt

This could be worse - they could be a lot more malicious and I could be in a more vulnerable position. I am positively festooned with privilege - so I don't have to worry about my physical safety, but it's annoying and distressing having to constantly filter them from my life.
