I want to force my users to use a

If youi could get this to work, you would have to have the 5 passwords stored somewhere in your front end file. This sounds like it would compromise the security of your passwords.

Look at nmci.com for a plugin that might do some of this.

Hi Kutulpa, something i did in a similar situation was to create a global number field in the front-end file called "enable" or something like that. Your open script in FrontEnd.fp5 has a step that sets enable to 1, and your closing script has a step that sets enable to 0.

In the opening script for each of the remaining files, the first step checks the value of enable through a relationship (calc field=1 in each file) and if the value is 0 it closes the application. This still allows users to get to the back-end files through the Window menu--to disable this, i'll echo Ralph in pointing you to nmci.com or securefm.com (same company, different URL).
