Just for the record: Google Authenticator implements an algorithm that is a public [standard](https://tools.ietf.org/html/rfc6238).

Note that Google Authenticator is just one example – there is a standard behind that called [TOTP](https://en.wikipedia.org/wiki/Time-based_One-time_Password_Algorithm) and all these Authenticator apps are compatible. Also, Google Authenticator does not contact Google servers, it’s entirely offline.
