Hello RetroK, please remember to give us your system infos when posting a question:

• "What do we need to solve your problem?"

You're talking about pop-ups, so I'm guessing you use some comfort panel or the RT Advanced.

If you use the user administration and a user clicks on a screen he has no right for the normal login dialogue appears.

• WinCC Advanced Manual "Configuring user administration"

 Can you use this and if not, why?

Normally you are not locking all elements in the screen, but all ways to get to the screen.

So if someone cklicks on the button which naviagtes to the locked Screen you can open a popup. There you could have an I/O field a "login" button.

You could use the following system functions in a script which you call when the user presses the "login" button:

• GetPassword
• GetUserName
• Logoff
• Logon
