# You need to have the "databases" file, available on Android here:
# /data/data/com.google.android.apps.authenticator2/databases/databases
# You will likely need a rooted Android to read this file
#
# Script requires pillow, fastqrcode and libqrencode-dev
# fastqrcode doesn't work with python 3.x :(
