Google Offers Built-In Security Key Feature for Android Phones

From PC Mag: Security keys can stop sophisticated phishing attacks from compromising your accounts, but most will set you back between $20-$50 per key. It's a big reason why the technology hasn't been widely adopted, but Google wants to change that by letting your Android phone act as a security key.

On Wednesday, Google began making the option available to those with a smartphone running Android 7.0 and up. The built-in security key functions like a hardware-based one, except it's free.

With this system, when you enter your password on the PC, a notification will be sent to the handset. You'll be asked to confirm that you want to sign in.
