Use Email as Username with ASP.NET Membership
Posted: 27 Dec 2012, 5:16am - ThursdayCouple of guides in the internet on using email as username with the ASP.NET Membership but the guide is too long and its a maze and crazy as hell for me. I found my own answer as simple as I wanted to. In my case, I created my own form. Form (View):
<form action="/home/authenticate" method="post" name="login">
<label>Email</label>
<input type="text" name="email" />
<br class="clear" />
<label>Password</label>
<input type="password" name="passwd" />
<br class="clear" />
<input type="submit" name="submit" value="Login" />
</form>
Authentication (Controller):
[HttpPost]
public ActionResult Authenticate()
{
Regex regex_email = new Regex(@"^(?("")("".+?""@)|(([0-9a-zA-Z]((\.(?!\.))|[-!#\$%&'\*\+/=\?\^`\{\}\|~\w])*)(?<=[0-9a-zA-Z])@))(?(\[)(\[(\d{1,3}\.){3}\d{1,3}\])|(([0-9a-zA-Z][-\w]*[0-9a-zA-Z]\.)+[a-zA-Z]{2,6}))$");
var email = Request.Form["email"];
var passwd = Request.Form["passwd"].Trim();
if ((!regex_email.IsMatch(email)) || (passwd.Length < 6))
{
return RedirectToAction("Index", "Home", new {
msg = "Invalid username or password!"
});
}
else
{
string username = Membership.GetUserNameByEmail(email);
if (Membership.ValidateUser(username, passwd))
{
FormsAuthentication.SetAuthCookie(username, true);
return RedirectToAction("Index", "Project");
}
else
{
return RedirectToAction("Index", "Home", new {
msg = "Invalid username or password!"
});
}
}
}
I just call the Membership.GetUserNameByEmail() then validate with Membership.ValidateUser().
That's it! Hope this help to others too.. :)
