When using Microsoft Edge to open the Privileged Access Service Admin Portal, users can only be authenticated silently when the browser has integrated Windows authentication enabled. For details, see Enabling Integrated Windows Authentication.
For Edge, a server is recognized as part of the local intranet security zone when the user specifies a URL with a fully qualified name that has been explicitly configured as a local intranet site in Edge (see instructions below). For example, if you access an application with a URL such as
http://acme.mycompany.com/index.html, Edge interprets this as a site that is not part of the local intranet unless the site has been manually added to the local intranet security zone.
Use the following procedure to enable silent authentication on each computer.
