A workgroup information file is a file about the users in a workgroup. Microsoft Access reads this file at startup. It contains information about account names, passwords, group membership and preferences. Preference information is specified in the Options dialog box.
A workgroup information file is initially created by the setup program when Microsoft Access is installed. The file is identified by the name and organisation information that is supplied during the setup process of Microsoft Access.
A Workgroup ID (WID) is created when a new workgroup information file is created. A WID can have between four and twenty characters and is case-sensitive. The WID guarantees that the workgroup file can't be recreated by another user by simply guessing the name and company. It also makes the Admins group unique to this workgroup file.

If you are serious about your Microsoft Access security, then you should check out Garry Robinson's book Real World Microsoft Access Database Protection and Security
About the book:
Microsoft Access is the most popular desktop database in the world today and its very popularity means that its security measures can be easily compromised. Real World Microsoft Access Database Protection and Security takes a different approach than all the other Access books in the market by focusing from the start on all the issues that will help protect your database. It approaches protection and security from a task-by-task perspective and provides details that when put together will make your database more secure.
This book will help you to keep your staff from looking at your salary tables, stop your customers from looking at the design of your software that you distribute, and help you decide which security options are worth doing and which are generally a waste of your time.
Garry writes from a very experienced developer's point of view and he discusses in detail how to program all types of security issues including hiding tables as system tables, producing databases that password cracker software cannot easily crack, backing-up databases, menus, queries, and even user surveillance.
