What is it?

An open-source library for creating, managing and using QR codes for two-factor authentication.

Why did we choose it?

It's open-source, well maintained, and does the job.

What do we use it for?

Generating QR codes to enable users to have two-factor authentication. This library lets us create the code itself, and then we use BaconQrCode to render an image from that QR code the user can scan.
