Modify certificate pinning for Australia Government Covidsafe Android Application
  1. Ensure your certificate for the MITM application is in PEM format. For example, Burp Suite generates the certificate in DER, so in this case, to convert from DER to PEM:
openssl x509 -inform der -in cacert.der -out cacert.pem

Note this certificate needs to also be installed on the Android device. Android expects DER format with the file extension .crt. If in doubt, consult google.com.

  1. Extract all three APKs. To avoid issues, -r is used.
apktool d -f -r au.gov.health.covidsafe.apk
apktool d -f -r config.xxhdpi.apk

Export TOTP tokens from Authy

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.
