Google is working on a new way to use Two-factor authentication (2FA) using QR codes. The new feature will be an improvement on the Android-based second-factor authentication that we already know about.

Web Authentication caBLE v2 QR codes

You might have noticed a prompt on your Android phone asking you to confirm when you log into your Google account from a new device. The new feature that I spotted today gives an additional method to confirm your identity.

The webpage requesting the second factor can display a QR code which you scan using your Android phone to approve sign-in.

Here is the experimental flag that I spotted today:

Web Authentication caBLE v2 QR codes: Enable display of QR codes for using Android phones as security keys

I could not find steps explaining how this might work. However, based on the flag description, users would scan QR codes to confirm sign-in.

Based on the number of comments on the feature request bug, this is a complex feature with a lot of moving parts and security concerns. It might take a while before we see this in action.

Stay tuned for more updates and screenshots about the new QR code-based second-factor authentication.
