ASP.NET identity use email instead of user name

Question

How can I use email instead of user name in the new ASP.NET identity system? I tried to change the `RegisterViewModel` class: ``` [Display(Name = "Email address")] [Required(ErrorMessage = "The email address is required")] [EmailAddress(ErrorMessage = "Invalid Email Address")] public string UserName { get; set; } ``` but when I enter an mail adress I am getting the error: ``` User name fsdfsd@fsdfsd.de is invalid, can only contain letters or digits. ```

Accepted Answer

You have 2 options to solve it by either turning off that validator, or create your own UserValidator.

You could turn it off like this:

```
UserManager.UserValidator = new UserValidator<TUser>(UserManager) 
                                    { 
                                       AllowOnlyAlphanumericUserNames = false 
                                    };
```
