Google has just confirmed that it is testing a new password-free method for logging in to the search giant's accounts. They simply have to respond to a notification that is sent to their smartphones. It is similar to Yahoo's Account Key system that requires a mobile app.

A Reddit user first discovered Google's testing of a smartphone-only sign-in system on December 22, Tuesday, according to The Sydney Morning Herald. Such a system would provide quicker access to Gmail, Google Drive, Chrome, YouTube, and other products from the search giant.

The tech titan's new login tech addresses the fact that account passwords are often one of the biggest security threats. There are various reasons. Some people use very basic or common passwords, or use the same password on different services.

One alternative is the two-factor authentication. However, many people consider it to be inconvenient as it adds another step to the log in process, which could involve a USB stick, or receiving a code through a text.

Here is how the new system works. When a person signs up for a Google account, they must enter their email address.

Then a notification will be sent to the person's smartphone asking if the person is attempting to sign in from a different device. They just have to tap "yes" on the phone's touchscreen, according to Tech Crunch.

Google told Tech Crunch that it is indeed testing a new no-password log in system. It has invited a small group of users to test it.  

There are a few major benefits of Google's new login system. It is ideal for people who have their phone nearby when they log in to other devices, and can also help to prevent phishing.

Google reported that the new system would be flexible. Users can still use their password, and link another phone number to their Google account.

Here are some of the worst passwords to use:
