#include <oath.h>
#include <ctime>
#include <iostream>
#include <string>

int main() {
    std::string secret = "YOUR_SECRET_KEY"; // User's unique secret key
    time_t currentTime = std::time(nullptr);

    char totpCode[10];
    oath_totp_generate(secret.c_str(), secret.length(), currentTime, 30, 0, 6, totpCode);

    std::cout << "TOTP Code: " << totpCode << std::endl;

    return 0;
}
