In your service / controller:
// inject the service
IOTPProvider otpProvider;
// generate a secret
var secret = "<some random string>";
// define the length of the password to generate
var passwordLength = 6;
// indicates whether the secret's spaces matter or not.
var ignoreSpaces = false; // false: Spaces matter. true: Spaces don't matter
var otp = otpProvider.GetPassword(secret, passwordLength, ignoreSpaces);
// the adjacent intervals to check for the OTP. The greater this value is, the higher risk of being hijacked.
