ASP.NET Identity 2 Remember Me - User Is Being Logged Out

Question

I am using Identity 2.1 in my MVC5 app. I am setting the isPersistent property of the PasswordSignInAsync to true to enable \'Remember Me\':

var result = await S         


        

Answer 1

I should write more. This strange code:

OnValidateIdentity = SecurityStampValidator
  .OnValidateIdentity(
  validateInterval: TimeSpan.FromMinutes(0),
  regenerateIdentity: (manager, user)
  => user.GenerateUserIdentityAsync(manager))

was causing my app to lost cookie after 1 day. I really don`t know why, but after excluding this code and adding a mashine key to my web.config "remember me" future is finally working right.

My current code is:

app.UseCookieAuthentication(new CookieAuthenticationOptions
{
   AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
   LoginPath = new PathString("/Account/Login"),
   ExpireTimeSpan = TimeSpan.FromDays(5)
});
