Google is testing out a new way to sign into their services — and it stops one of the most annoying security measures out there: passwords. The tech giant is trying out a feature that lets some users confirm their identity just by using their smartphones（智能手机）.

The move is not only just the latest sign that the tech industry is trying to get users away from passwords. It's also the latest sign that companies still aren't quite sure how to replace them yet. Passwords are almost impossible to escape right now, but keeping track of the dozens you need just to navigate your daily online life can be maddening.

And they’re also almost universally hated: Creating strong, unique passwords can feel like pulling teeth and reusing them can leave you vulnerable（容易受伤的）when a service you rely on gets breached. Moreover, data from those almost inevitable breaches shows that people keep sticking to ridiculously easy-to-guess passwords like “123456” or, well, “password.”

“Right now it’s relatively convenient to have a simple password,”said Alvaro Bedoya, the executive director of Georgetown Law's Center on Privacy & Technology. “But as hacks increase and breaches proliferate（激增）, people are starting to realize that also may be dangerous.”Many big sites and services now offer two-factor authentication — an added layer of protection that often works by making you enter a code that's delivered to your phone via text messages or an app.

Google’s new test seems to be a lot like just taking the password part out of this common two-factor equation — and it appears to be very similar to a system Yahoo launched for its mail app users earlier this year.
