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 had this issue. It was caused by my custom UserStore not implementing IUserSecurityStampStore.

public Task GetSecurityStampAsync(IdentityUser user)
{
    return Task.FromResult(user.SecurityStamp);
}

Without a security stamp the SecurityStampValidator has nothing to validate and so logs out the user.
