Tried to use the code generated to login, but it kept saying it is not working. Eventually I had to open my phone Google Authenticator and used the code generated instead and it worked. The codes generated from the Google Authenticator within phone are different to the ones generated in this App and the websites that use 2FA only accept the ones from my phone. Therefore this Google Authenticator Chrome extension app is now useless when it supposes to work the same as Google Authenticator.
