After you log in to the Registry, authentication happens transparently whenever you try to add, delete, or modify a Registry object, because any write request triggers authentication based on the client certificate loaded into your web browser.
After authentication is completed, access to the Registry is over https .
When your session expires, you are no longer authenticated by the Registry. A subsequent write request prompts the Web Console to re-authenticate you.
If authentication fails, stop and restart your web browser and try again.
