How to log in with username instead of email address in Identity Web Forms ASP.Net

Question

I need my login to use a username instead of an email address, how can I change it? I searched everywhere, but they are MVC codes, not web forms.

I appreciate your efforts to achieve a solution to my problem.

using System; using System.Web; using System.Web.UI; using Microsoft.AspNet.Identity; using Microsoft.AspNet.Identity.Owin; using Owin; using Web_WebApp.Models; namespace Web_WebApp.Account { public partial class Login : Page { protected void Page_Load(object sender, EventArgs e) { RegisterHyperLink.NavigateUrl = "Register"; // Enable this once you have account confirmation enabled for password reset functionality //ForgotPasswordHyperLink.NavigateUrl = "Forgot"; OpenAuthLogin.ReturnUrl = Request.QueryString["ReturnUrl"]; var returnUrl = HttpUtility.UrlEncode(Request.QueryString["ReturnUrl"]); if (!String.IsNullOrEmpty(returnUrl)) { RegisterHyperLink.NavigateUrl += "?ReturnUrl=" + returnUrl; } } protected void LogIn(object sender, EventArgs e) { if (IsValid) { // Validate the user password var manager = Context.GetOwinContext().GetUserManager<ApplicationUserManager>(); var signinManager = Context.GetOwinContext().GetUserManager<ApplicationSignInManager>(); // This doen't count login failures towards account lockout // To enable password failures to trigger lockout, change to shouldLockout: true var result = signinManager.PasswordSignIn(UserName.Text, Password.Text, RememberMe.Checked, shouldLockout: false); switch (result) { case SignInStatus.Success: IdentityHelper.RedirectToReturnUrl(Request.QueryString["ReturnUrl"], Response); break; case SignInStatus.LockedOut: Response.Redirect("/Account/Lockout"); break; case SignInStatus.RequiresVerification: Response.Redirect(String.Format("/Account/TwoFactorAuthenticationSignIn?ReturnUrl={0}&RememberMe={1}", Request.QueryString["ReturnUrl"], RememberMe.Checked), true); break; case SignInStatus.Failure: default: FailureText.Text = "Invalid login attempt"; ErrorMessage.Visible = true; break; } } } } }

Answer 1

You can simply find the user by username or whatever you want, and then log in directly using the SignIn method:

 protected void LogIn(object sender, EventArgs e) { if (IsValid) { // Validate the user password var manager = Context.GetOwinContext().GetUserManager<ApplicationUserManager>(); var signinManager = Context.GetOwinContext().GetUserManager<ApplicationSignInManager>(); // assuming you have a text box named UserName var user=manager.FindByName(UserName.Text); // or for advanced scenarios you can write: // var user = manager.Users.FirstOrDefault(u => u.UserName == UserName.Text); if(user !=null) { if(manager.CheckPassword(user, Password.Text)) { signinManager.SignIn(user, false, RememberMe.Checked); IdentityHelper.RedirectToReturnUrl(Request.QueryString["ReturnUrl"], Response); } } } FailureText.Text = "Invalid login attempt"; ErrorMessage.Visible = true; } 

Answer 2

If you look at the SignInManagerExtensions.PasswordSignIn MSDN , this will tell you that the first argument in the PasswordSignIn method is userName .

MVC and WebForms set this by default by email when you register with an email address. You can also change the action in the register to allow registration using UserName, this by default adds the username and username to the database.

 protected void CreateUser_Click(object sender, EventArgs e) { // ... // UserName and Email are both set to Email.text // Add a UserName TextBox and Replace UserName = Email.Text with UserName = UserName.Text var user = new ApplicationUser() { UserName = Email.Text, Email = Email.Text }; // ... } protected void LogIn(object sender, EventArgs e) { if (IsValid) { // ... // The first argument is userName // Replace mail.Text with UserName.Text var result = signinManager.PasswordSignIn(mail.Text, Password.Text, RememberMe.Checked, shouldLockout: false); // .. } } 

Replace:

 <div class="form-group"> <asp:Label runat="server" AssociatedControlID="Email" CssClass="col-md-2 control-label">Email</asp:Label> <div class="col-md-10"> <asp:TextBox runat="server" ID="Email" CssClass="form-control" TextMode="Email" /> <asp:RequiredFieldValidator runat="server" ControlToValidate="Email" CssClass="text-danger" ErrorMessage="The email field is required." /> </div> </div> 

WITH

 <div class="form-group"> <asp:Label runat="server" AssociatedControlID="UserName" CssClass="col-md-2 control-label">UserName</asp:Label> <div class="col-md-10"> <asp:TextBox runat="server" ID="UserName" CssClass="form-control" /> <asp:RequiredFieldValidator runat="server" ControlToValidate="UserName" CssClass="text-danger" ErrorMessage="The username field is required." /> </div> </div> 

Hope this makes sense.
