AntiForgeryConfig

One way to solve it is to set AntiForgeryConfig to use other ClaimType.

protected void Application_Start()
{
    AreaRegistration.RegisterAllAreas();

    WebApiConfig.Register(GlobalConfiguration.Configuration);
    FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
    RouteConfig.RegisterRoutes(RouteTable.Routes);
    BundleConfig.RegisterBundles(BundleTable.Bundles);

    AntiForgeryConfig.UniqueClaimTypeIdentifier = ClaimTypes.Email;
}

Add NameIdentifier and IdentityProvider ClaimTypes

Alternatively, you can add NameIdentifier and IdentityProvider ClaimTypes to your claims.

List _claims = new List();
_claims.AddRange(new List
{
    new Claim("http://schemas.xmlsoap.org/ws/2005/05/identity/claims/nameidentifier", _user.Email)),
    new Claim("http://schemas.microsoft.com/accesscontrolservice/2010/07/claims/identityprovider", _user.Email)
})
