    // options.UseMemoryCacheStorageProvider(); // -> It relies on the server's times. It's safer than the CookieStorageProvider.
    .UseCookieStorageProvider(SameSiteMode.Strict /* If you are using CORS, set it to `None` */) // -> It relies on the server and client's times. It's ideal for scalability, because it doesn't save anything in the server's memory.
