ASP.NET (C#) Question

.NET Identity Email/Username change

Does anyone know how to enable a user to change username/email with ASP.NET identity with email confirmation? There's plenty of examples on how to change the password but I can't find anything on this.

This should do the trick for you:

// get user object from the storage
var user = await userManager.FindByIdAsync(userId);

// change username and email
user.Username = "NewUsername";
user.Email = "";

// Persiste the changes
await userManager.UpdateAsync(user);

// generage email confirmation code
var emailConfirmationCode = await userManager.GenerateEmailConfirmationTokenAsync(user.Id);

// generate url for page where you can confirm the email
var callbackurl= "";

// append userId and confirmation code as parameters to the url
callbackurl += String.Format("?userId={0}&code={1}", user.Id, HttpUtility.UrlEncode(emailConfirmationCode));

var htmlContent = String.Format(
        @"Thank you for updating your email. Please confirm the email by clicking this link: 
        <br><a href='{0}'>Confirm new email</a>",

// send email to the user with the confirmation link
await userManager.SendEmailAsync(user.Id, subject: "Email confirmation", body: htmlContent);

// then this is the action to confirm the email on the user
// link in the email should be pointing here
public async Task<ActionResult> ConfirmEmail(string userId, string code)
    var confirmResult = await userManager.ConfirmEmailAsync(userId, code);

    return RedirectToAction("Index");
