Users can reset a device for their own account, and do not need administrator approval or permission to reset a Google TOTP registration. Google Authenticator is a software-based authenticator by Google that implements two-step verification services using the Time-based One-time Password Algorithm (TOTP; specified in RFC 6238) and HMAC-based One-time Password algorithm (HOTP; specified in RFC 4226), for authenticating users of software applications. Risky Choice for 2FA Using an authenticator app for 2FA is seen as a top choice for securing access to sensitive accounts over other methods. However, when the app stops loading, and instead crashes on open, you can easily lose access to these accounts if you’re relying on the app for 2FA and you don’t have backup methods configured (or physically accessible to you in the moment).

TOTP synchronization problem. A TOTP hardware token is completely offline, no network connection whatsoever. This makes it impenetrable for the majority of known hacker attacks. But the TOTP algorithm relies on the time, so the tokens are supplied with a clock of sorts — an oscillator. With no way to sync the time, a drift happens eventually.

I need the following : I need a clean APIs convert the code to Java and package it as Library (POJO classes only) .
