Yahoo's New Authentication Program Available for U.S. Users

Yahoo announced a new authentication option at South by Southwest Sunday that would let users log in to their accounts without a password. It's now available for U.S. users, a Yahoo news release said. Passwords are texted directly to a user’s mobile phone during the sign-in process under this new authentication system, which Yahoo hopes will “ease anxiety around password memorization and improve security for users,” the release said. Users must opt in to receive “on-demand” passwords, Yahoo said.
