How can I use xDB contact to login users?

Question

I'm tracking visitors information into my mongoDB and I can identify them as contacts (through the email). I'm now trying to have a login (with password) area where users can login and see some information. I'm not clear how can I do this? Can I still use my mongoDB Contact or is this different?

Once you log the user in, you can process some out of the box Sitecore facets or your custom ones.

Setting the user's info in xDB

[HttpPost]
[AllowAnonymous]
public ActionResult Login(LoginModel model, string returnUrl)
{
  if (ModelState.IsValid)
  {
    Sitecore.Security.Domains.Domain domain = Sitecore.Context.Domain;
    string domainUser = domain.Name + @"\" + model.UserName;
    if (Sitecore.Security.Authentication.AuthenticationManager.Login(domainUser, model.Password, model.RememberMe))
    {
      AnalyticsHelper.SetVisitTagsOnLogin(domainUser, false);
      return RedirectToLocal(returnUrl);
    }
  }

  // If we got this far, something failed, redisplay form
  ModelState.AddModelError("", "The user name or password provided is incorrect.");
  return View(model);
}

A helper function to assign the user's data to the xDB facets.

public static void SetVisitTagsOnLogin(string domainUser, bool IsNewUser)
{
    string name = Sitecore.Context.User.Profile.FullName;
    if (name == String.Empty) name = Sitecore.Context.User.LocalName;
    Tracker.Current.Contact.Tags.Add("Username", domainUser);
    Tracker.Current.Contact.Tags.Add("Full name", name);

    Tracker.Current.Contact.Identifiers.AuthenticationLevel = AuthenticationLevel.PasswordValidated;
    Tracker.Current.Session.Identify(domainUser);

    if (IsNewUser)
    {
        IContactPersonalInfo personalFacet = Tracker.Current.Contact.GetFacet<IContactPersonalInfo>("Personal");
        personalFacet.FirstName = GetFirstName(name);
        personalFacet.Surname = GetSurName(name);

        IContactEmailAddresses addressesFacet = Tracker.Current.Contact.GetFacet<IContactEmailAddresses>("Emails");
        IEmailAddress address;
        if (!addressesFacet.Entries.Contains("work_email"))
        {
            address = addressesFacet.Entries.Create("work_email");
            address.SmtpAddress = GetEmailAddressFromUser(domainUser);
            addressesFacet.Preferred = "work_email";
        }
    }
}

Getting the user's info out of xDB

The benefit of xDB is that all the user's facet data is on there current contact object. Just call for the facet to get the data.

var contact = Tracker.Current.Contact;
var emailAddresses = contact.GetFacet<IContactEmailAddresses>("Personal");

You can find some more information about getting the facet data here. http://sitecore-community.github.io/docs/xDB/contact-facets/

As described on this page, https://doc.sitecore.net/sitecore_experience_platform/setting_up__maintaining/xdb/contacts/identifying_contacts. The domain user in the code above can be:

• A user login name
• A user ID in a security system
• An email address
