How To Generate 2FA Codes With Spring Boot And Google Authenticator

Hey, fam! In this tutorial, I'll demo how to generate time-based one-time passwords (TOTP) with Spring Boot so these can be used for 2-factor authentication (2FA). Based on a shared secret, I'll create a QR code that is understood by Google Authenticator and exposed using a RestController, so the codes can be managed with it.

Very nice tutorial, but I have a question, currently, the Google Authenticator project has been archived; Do you know what is the new repo? Thanks!
