Google Tests Signing Into Accounts Using Your Phone, No Password Required (venturebeat.com)

An anonymous reader writes: Google's battle against poor passwords continues. The company is now testing a new Google Account option that lets users login using their phone, skipping the part where you have to enter your password. The feature uses your phone to authenticate your identity by bringing up a notification that allows you to grant or deny access to your account. Google confirmed it was testing the feature with a small group of users.

Single factor authentication

This is still single-factor authentication. All they've done is change from "something you know" to "something you have". And, since that "something you have" can break or get lost or stolen, I'm not sure they haven't just replaced one problem with another.

Passwords suck, but nobody can steal your password from your work/library/restaurant table while you're off taking a dump (or whatever).
