Turn your Android smartphones into account security keys

Google has expanded its two-factor authentication offering for Android smartphones, making it even easier to authenticate your account logins.

The company announced in a blog post that you Android smartphone can now be used as 2FA key when logging into another device.


To activate your smartphone’s built-in security key, you will need a handset running Android 7.0 or above and a Bluetooth-enabled ChromeOS, macOS X, or Windows 10 computer with a Chrome browser.

Here is How to do It

  • Add your Google Account to your Android phone.
  • Make sure you’re enrolled in 2-step verification
  • On your computer, visit the 2SV settings and click “Add security key”.
  • Choose your Android phone from the list of available devices—and you’re done!

Once this is completed, users can authenticate login attempts by holding down the volume down button on their smartphone when prompted.

This will roll out in a few days for everyone in beta.
