I am to share with you this alternative to receive the codes, I find it very useful for those who do not want to use the android App.

https://2fa-auth.com/ is compatible with Google Authenticator

Just paste the key, and it will generate the same code as the Google App.

If you use several accounts, as in my case, you can paste several keys and it will give you the different codes.

If you know any extension for Google Chrome that works the same and is compatible with the codes given by Google, I would appreciate it.
