member this.CustomCredential : string
Public ReadOnly Property CustomCredential As String

Examples

The following example shows an event handler for the CreatingCookie event. The handler retrieves user values from the CreatingCookieEventArgs object in order to customize the authentication cookie. The value passed in the CustomCredential property is stored in the UserData property of the forms authentication ticket.

Note

Store the CustomCredential property in a cookie only when you know that the data in the property is not sensitive. Malicious users can access the values in the cookie.

void AuthenticationService_CreatingCookie(object sender, 
    System.Web.ApplicationServices.CreatingCookieEventArgs e)
{
    FormsAuthenticationTicket ticket = new
          FormsAuthenticationTicket
            (1,
             e.UserName,
             DateTime.Now,
             DateTime.Now.AddMinutes(30),
             e.IsPersistent,
             e.CustomCredential,
             FormsAuthentication.FormsCookiePath);

    string encryptedTicket =
         FormsAuthentication.Encrypt(ticket);

    HttpCookie cookie = new HttpCookie
         (FormsAuthentication.FormsCookieName,
          encryptedTicket);
    cookie.Expires = DateTime.Now.AddMinutes(30);

    HttpContext.Current.Response.Cookies.Add(cookie);
    e.CookieIsSet = true;
}
Sub AuthenticationService_CreatingCookie(ByVal sender As Object, _
                 ByVal e As System.Web.ApplicationServices.CreatingCookieEventArgs)
    Dim ticket As FormsAuthenticationTicket = New _
       FormsAuthenticationTicket _
        (1, _
         e.Username, _
         DateTime.Now, _
         DateTime.Now.AddMinutes(30), _
         e.IsPersistent, _
         e.CustomCredential, _
         FormsAuthentication.FormsCookiePath)
        
    Dim encryptedTicket As String = FormsAuthentication.Encrypt(ticket)
    
    Dim cookie As HttpCookie = New _
        HttpCookie(FormsAuthentication.FormsCookieName, encryptedTicket)
    cookie.Expires = DateTime.Now.AddMinutes(30)
    
    HttpContext.Current.Response.Cookies.Add(cookie)
    e.CookieIsSet = True
End Sub

Remarks

You use the CustomCredential property to retrieve custom values in the authentication ticket. The CustomCredential property contains the value passed to the Login method. Typically, this property is used to pass custom values that must be validated with the user name and password, such as an identification number. If more than one value is stored in the property, you must parse the CustomCredential property in order to retrieve values.
