Background
All of the web pages and scripts that TIM Plus 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 their 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 practise 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

Solution
Although including the username and password in a URL is disabled by default on Windows Internet Explorer since it is considered a security risk, you can override this restriction by making the following changes to the Windows Registry.
| Tip |
|---|
| Since you'll be exposing a username and password as part of a URL, it is recommended that you create a dedicated web user object inside the TIM Enterprise Plus directory that will be used solely for this purpose. See Adding/Removing Web Users the Web users page for details of how to set up a web user. |

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.)
