Twitter adds two-factor authentication

by Curtis Lee Fulton

Twitter has joined Google in adding two-factor authentication to sign-ons. The company says that when a user signs into Twitter, “there’s a second check to make sure it’s really you. You’ll be asked to register a verified phone number and a confirmed email address.”

The upgrade has provoked Internet libertine Kim Dotcom to brag about his two-factor authentication patent, claiming Twitter is in violation.
