Your Phone Number Shouldn't Be Your Identity

Brian Krebs wrote a good article on how our phone numbers have become security and authentication tools, and thus closely tied to our identity. But there’s a problem with that.

Phone numbers stink for security and authentication. They stink because most of us have so much invested in these digits that they’ve become de facto identities. At the same time, when you lose control over a phone number — maybe it’s hijacked by fraudsters, you got separated or divorced, or you were way late on your phone bill payments — whoever inherits that number can then be you in a lot of places online.
