Android smartphones can be used as keys for two-factor authentication

Android-смартфоны могут использоваться как ключи для двухфакторной аутентификации

Google has announced that any smartphone on Android Nougat 7.0 and newer will be able to work as a physical security key for two-factor authentication. To secure confirmation of authorization on sites no longer need to buy a separate dongle.

The feature works in Gmail, G Suite, Google Cloud and other services of the company and uses the authentication standard FIDO.

To activate the security key of the smartphone will need a computer with Chrome OS, Windows or macOS and Bluetooth:

  • Add a Google account on the smartphone
  • Make sure that you have enabled two-factor authentication
  • Connect your smartphone to the computer via Bluetooth
  • Select from the «security Key» smartphone from the list

In addition to physical key, Google offers other ways to protect SMS code, token in the Authenticator application, a confirmation from the Google Prompt, and spare codes.

Google Pixel 3 and 3 XL confirm authorization by pressing the volume buttons: FIDO data are stored in a special Titan M chip built into the smartphone, and the module checks whether a key has been pressed.

Two-factor authentication allows you to protect your account from hacking. Even if the attacker knows the username and password to login he will need one more parameter — either an SMS code or confirmation to a physical device.
