Use an Android phone as a security key for 2-Step Verification

This announcement was made at Google Cloud Next ‘19 in San Francisco. Check out Next OnAir to tune into the livestream or watch session recordings following the event.

What’s changing

We’re adding an option to use your Android phone’s built-in security key for multi-factor authentication in G Suite. All phones running Android 7.0+ (Nougat) have a built-in key which can be activated. This means your users can use existing phones as a primary 2-Step Verification method to protect against phishing. Using a phone as a security key is currently offered in beta.

Why you’d use it 

2-Step Verification greatly improves the security of your account by adding another layer to your account security and making it more resistant to phishing attacks. By adding the additional option of using your Android phone’s built-in security key, we’re expanding access to phishing-resistant 2-Step Verification method in a convenient form - your phone. This can make it faster for you to implement 2-Step Verification in your organization while keeping user training and overall costs to a minimum. 

Previously, in order to protect your users against password phishing, the only option was to use a security key fob. With this beta, their mobile phone can be that security key.
