Asp.Net MVC 5

How do I implement forgot password in Asp.Net MVC 5?

Hello everyone, I am going to share the code sample with simple steps for forgot a password or reset the password using Asp.Net MVC 5.

Following steps of forgot the password as given below:-
1.      The First click on forgot links
2.      Enter valid emailId in the input text box
3.      Validate emailId, If email valid sent an email to given email with attached links
4.      Click on given email links, open a popup with new pwd and confirm pwd
5.      Click on reset pwd, If valid pwd then sent successfully msg on below popup box, otherwise send error msg for an invalid attempt

Example in detail step by step:-

Click on forgot a link and enter the email, if an input email is a valid system will send you an email link to your given emailId.

Forgot password HTTP post action method:-
        [HttpPost]
        [AllowAnonymous]
        [ValidateAntiForgeryToken]
        public async Task<ActionResult> ForgotPassword(ForgotViewModel model)
        {
            if (ModelState.IsValid)
            {
                var user = await UserManager.FindByNameAsync(model.UserName);

                string To = model.UserName, UserID, Password, SMTPPort, Host;
                if (user == null)
                {
                    //If user does not exist or is not confirmed.
                    return View("ForgotPassword");
                }
                else
                {
                    //Generate password token
                    var guid = Guid.NewGuid();

                    //Create URL with an above token
                    var lnkHref = "<a href='" + Url.Action("ResetPassword", "Account", new { email = model.UserName, code = guid }, "http") + "'>Reset Password</a>";

                    //HTML Template for Send email
                    string subject = "Your changed password";
                    string body = "<b>Please find the Password Reset Link. </b><br/>" + lnkHref;


                    //Get and set the app settings using configuration manager.
                    EmailManager.AppSettings(out UserID, out Password, out SMTPPort, out Host);

                    //Call send email methods.
                    EmailManager.SendEmail(UserID, subject, body, To, UserID, Password, SMTPPort, Host);
                }
            }
            return View();
        }

Email Manager Class:-

public class EmailManager
{
    public static void AppSettings(out string UserID, out string Password, out string SMTPPort, out string Host)
    {
        UserID = ConfigurationManager.AppSettings.Get("UserID");
        Password = ConfigurationManager.AppSettings.Get("Password");
        SMTPPort = ConfigurationManager.AppSettings.Get("SMTPPort");
        Host = ConfigurationManager.AppSettings.Get("Host");
    }

    public static void SendEmail(string From, string Subject, string Body, string To, string UserID, string Password, string SMTPPort, string Host)
    {
        System.Net.Mail.MailMessage mail = new System.Net.Mail.MailMessage();
        mail.To.Add(To);
        mail.From = new MailAddress(From);
        mail.Subject = Subject;
        mail.Body = Body;
        SmtpClient smtp = new SmtpClient();
        smtp.Host = Host;
        smtp.Port = Convert.ToInt16(SMTPPort);
        smtp.Credentials = new NetworkCredential(UserID, Password);
        smtp.EnableSsl = true;
        smtp.Send(mail);
    }
}

App setting for the configuration manager:-

  <appSettings>
    <add key="ToEmail" value="anil@gmail.com" />
    <add key="UserID" value="anil@gmail.com" />
    <add key="Password" value="enterpassordhere" />
    <add key="SMTPPort" value="587" />
    <add key="Host" value="smtp.gmail.com" />
  </appSettings>

After Click on the given email link, open a popup with new pwd and confirm pwd. If the attempt is valid then sent successfully msg on below popup box otherwise send error msg for an invalid attempt.

    /// <summary>
    /// this method is used to handle the post events for ResetPassword.
    /// </summary>
    [HttpPost]
    [AllowAnonymous]
    public ActionResult ResetPassword(ResetPwdViewModel model, string email, string code)
    {
        if (ModelState.IsValid)
        {
            AspNetUser user = _repoAspDotNetUser.GetAspNetUser(email);
            if (user != null)
            {
                String hashedNewPassword = userManager.PasswordHasher.HashPassword(model.Password);
                bool result = _repoAspDotNetUser.ResetPasswordByToken(email, code, hashedNewPassword);
                if (result)
                {
                    ModelState.AddModelError("", "Please return to the login page and enjoy with new password.");
                }
            }
            else
            {
                ModelState.AddModelError("", "It's not a valid, this attempt is already processed.");
            }
        }
        return View();
    }
