The two-factor authentication or 2FA is really a security measure that everyone should implement on their accounts to avoid the worst in case of password leakage.

It consists in getting on your smartphone a unique number that changes every 30 seconds. There are many 2FA applications but among the most famous, there is of course Authy from Twilio and Google Authenticator.

Authy has a backup module but Google Authenticator does not. Instead, there is an export possibility that you have to think about and that displays a unique QR Code containing all your accounts. And of course you'll have to scan it again with Google Authenticator to get everything back at once.

But how to get the otpauth links unique to each of the imported sites to be able to import them in another 2FA client?

Well, there is a script called Gauth-Export which allows you to retrieve all the otpauth URIs of each of your sites from the Google Authenticator export QR code or from its otpauth-migration link. It's very useful to make a smooth migration to another two-factor manager like Authy, Lastpass Authenticator or others.

You can get this script directly on Github
