on a event on which u want to send otp put the below code..
Random rnd = new Random();
int otp = rnd.Next(1000,9999);
ViewState["msgotp"]=otp;
string msg="your otp from abc.com is "+otp;
bool f=SendOTP("[email protected]","[email protected]","Subjected to OTP",msg);
if(f)
{ response.write("otp sent successfully"); }
else { response.write("otp not sent"); }
and then compare the otp entered by user with ViewState["msgotp"]
if(textBox3.text==ViewState["msg"].toString())
{
/////authorized person
} else
{
//// user entered wrong otp
}
/////below method is for sending mail just put an smtp according to your mail server
public bool SendOTP(string from,string to,string subject,string body)
{
bool f=false;
try
{
MailMessage mailMessage = new MailMessage();
mailMessage.To.Add(to);
mailMessage.From = new MailAddress(from);
mailMessage.Subject =subject;
mailMessage.Body = body;
SmtpClient smtpClient = new SmtpClient("smtp.your-isp.com");
