In fact, Google Authenticator has nothing to do with Google services. What you need to look for is TOTP. Research again using TOTP and rfc6238 as keywords and you will find lots of resources.

Java library for google authenticator was implemented and can be found here, https://github.com/wstrange/GoogleAuth

Sorry if this is too much of a necro-post, but I found this library on GitHub - maybe it can help you (and others looking for the same). :)

Note: this is not an official Google library, but it follows the RFC 6238 spec for Time-based One-time Password (TOTP), and the author looked at the C code for Google Authenticator for reference.
