By adding the required Plesk domain user, IIS user, and IIS WP user with proper permissions, the website can be accessed normally without authentication prompts. After applying the permission changes, always verify the website in the browser to confirm that the issue is resolved.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Introduction Sometimes, when accessing a website hosted in Plesk through a browser, a pop-up may appear asking for a username and password.
