Quickly generate QR codes for Google Authenticator

auth_qr_codes.bash

#!/bin/env bash

###
# Quickly generate QR codes to easily repopulate Google Authenticator.
# To use this, you'll have to have recorded your auth secret when you activated
#   multi-factor authentication. When run, this script will draw QR codes into
#   your terminal, which you can then scan with Google Authenticator.
#
# NB: These secrets should be treated with the same care as your password. I recommend
#   you keep this file encrypted when not in use.
#
# REQUIRES: python module 'qrcode' -- https://pypi.python.org/pypi/qrcode

# IMPORTANT: Prefix each line with a space so it isn't logged in your bash history.

# Use the format below, replacing USERNAME, SECRET, and SITE with appropriate values.
# Repeat the command for each site you want to add to Authenticator.
