How to fix google authenticator not scanning barcode

This is a rather weird random bug. Sometimes your google authenticator app won’t scan the barcode (QR) during setting up two-factor authentication (2FA). This happened to me on my Pixel 2 XL. I tried zooming the webpage, taking screenshot of the barcode (QR). The solution was rather simple.

Solution

You need to hold your phone far away to scan the QR code. Really far away, 2-3 ft or 1m away from the QR code. When the code looks way too small on your phone screen, it will work.
