No, the server audits all events specified for the user regardless of the application. Are you auditing logins for the user you specified when prompted for login in the Workflow Admin Console? (Pedantic aside: the user is not a "normal user", it needs to have Manage Trustees privilege in order to allow WF to set the password for WFUser$)
The most likely cause for an unexpected change of password for WFUser$ is a second WF Subscriber was configured to monitor the repository and reset the password. Other ways to change the user's password like SDK scripts or direct SQL edits are a lot less likely. If that second subscriber is still connected (unlikely because you changed the password already), you may be able to see from the session listed the Laserfiche Admin Console and see which machine it's coming from. Then on that machine, Workflow's service.log (in the install folder under Logs) will tell you who did it. There should be a line in it saying something like "user so and so configured repository X", just search for the repository name.
