        {
            Provider = new CookieAuthenticationProvider
            {
                OnValidateIdentity = SecurityStampValidator.OnValidateIdentity<ApplicationUserManager, ApplicationUser>(
        validateInterval: TimeSpan.FromMinutes(15)
            },

IdentityOptions:

services.AddIdentity<AppUser, AppRole>(options =>
{
    options.SecurityStampValidationInterval = TimeSpan.FromMinutes(15);
}

CookieAuthenticationEvents:

app.UseCookieAuthentication(new CookieAuthenticationOptions()
{
    Events = new CookieAuthenticationEvents()
    {
        OnValidatePrincipal = context =>
        {
            Microsoft.AspNet.Identity.SecurityStampValidator.ValidatePrincipalAsync(context);
            return Task.FromResult(0);
        },
    },
    ExpireTimeSpan = TimeSpan.FromMinutes(30)
});
