Exporting your 2FA tokens from Authy to transfer them into another 2FA application

IMPORTANT - Update regarding deprecation of Authy desktop apps

Past August 2024, Authy stopped supported the desktop version of their apps:
See Authy is shutting down its desktop app | The 2FA app Authy will only be available on Android and iOS starting in August for details.

And indeed, after a while, Authy changed something in their backend which now prevents the old desktop app from logging in. If you are already logged in, then you are in luck, and you can follow the instructions below to export your tokens.

If you are not logged in anymore, but can find a backup of the necessary files, then restore those files, and re-install Authy 2.2.3 following the instructions below, and it should work as expected.

# The reason of creating this script is that Endpoint Security VPN installs it's own application firewall kext cpfw.kext
# which prevents for example PPTP connections from this computer, which is not appropriate if you need subj connection just
# from time to time
#
# Usage: ./checkpoint.sh
#
# The script checks if Enpoint Security VPN is running. If it is, then it shuts it down, if it is not, it fires it up.
# Or, make an Automator action and paste the script.
