How to create code Jscript using Testcomplete for 3 different users should login and see the authorization page

I had the same problem as you. If it's the best way, I do not know, but I created a file called "user.pwd" and put it in a folder on the local computer. After that, I created a function that reads the file containing the password and used it during the execution of scripts. In this way, each developer could have a file with the password on your machine that script always searches in a local directory.
