see, OTP just means a random number or combination of random numbers and alphabets, so generating OTP is not a big deal, the thing that matters is, how will you send that number to a particular phone number, because you are not sending with your phone where you have networks like airtel or JIo, so you need an API. for OTP generation you can use your own logic like private string GenerateRandomOTP( int iOTPLength,string[] saAllowedCharacters ) { string sOTP = String.Empty; string sTempChars = String.Empty; Random rand = new Random(); for ( int i = 0; i { int p = rand.Next(0, saAllowedCharacters.Length); sTempChars = saAllowedCharacters[rand.Next(0, saAllowedCharacters.Length)]; sOTP += sTempChars; } return sOTP; } public string SendOTP(){ string[] saAllowedCharacters = { "1" , "2" , "3" , "4" , "5" , "6" , "7" , "8" , "9" , "0" }; return GenerateRandomOTP(8, saAllowedCharacters); }
