Background
All of the web pages and scripts that TIM Enterprise serves are protected by a login that is provided by a user when entering their username and password into a pop-up dialog presented by the web browser.
In some situations, it is desirable to suppress this dialog box demanding the username and password. An example might be the deployment of a stand-alone computer displaying a pre-defined wallboard on a large screen - it would become tedious having to log in to the web page every time that computer is restarted.
Different web browsers behave differently when asked to automatically log in to web sites. Variously, they range from complete prohibition of the practice to permitting it only if certain system parameters are configured.
e.g. Chrome + Firefox have plugins that allow auto login :-
Chrome - Auto Login
https://chrome.google.com/webstore/detail/auto-login/kjdgohfkopafhjmmlbojhaabfpndllgk?hl=en
Firefox - Auto Auth

Updates
Microsoft has removed the ability to auto login using regedit. They've patched it :-
https://docs.microsoft.com/en-us/security-updates/securitybulletins/2004/ms04-040
(As with the previous Internet Explorer Cumulative Security Update, MS04-004, this update prevents you from visiting Web sites that have "username:password@host.com" URLs for XMLHTTP. We have created an update to MSXML that addresses this issue specifically for XMLHTTP. For more information, see Microsoft Knowledge Base Article 832414.)
