Set user-level security. Remove user-level security. Object permissions reference. Access and later versions provides user-level security only for databases that use Access and earlier file formats.
In later versions, if you open a database created in an earlier version of Access, and that database has user-level security applied, that security feature will work as designed for that database. For example, users must enter a password to use the database. In addition, you can start and run the various security tools provided by Access and earlier versions, such as the User-Level Security Wizard and the various user and group permission dialog boxes.
As you proceed, remember that those tools become available only when you open an. If you convert the files to the. The following sections provide background information about user-level security in Access and earlier versions. If you are already familiar with the previous security model and user-level security, you can skip these sections and go directly to Set user-level security or Remove user-level security , later in this article.
User-level security in Access resembles the security mechanisms on server-based systems — it uses passwords and permissions to allow or restrict the access of individuals, or groups of individuals, to the objects in your database. In Access or earlier versions, when you implement user-level security in an Access database, a database administrator or an object's owner can control the actions that individual users, or groups of users, can perform on the tables, queries, forms, reports, and macros in the database.
For example, one group of users can change the objects in a database, another group can only enter data into certain tables, and a third group can only view the data in a set of reports. User-level security in Access and earlier versions uses a combination of passwords and permissions — a set of attributes that specifies the kinds of access that a user has to the data or objects in a database.
You can set passwords and permissions for individuals or groups of individuals, and those combinations of passwords and permissions become security accounts that define the users and groups of users who are allowed access to the objects in your database. In turn, the combination of users and groups is known as a workgroup, and Access stores that information in a workgroup information file. At startup, Access reads the workgroup information file and enforces the permissions based on the data in the file.
By default, Access provides a built-in user ID and two built-in groups. In turn, the Users group has full permissions on all the objects in a database. In addition, the Admin ID is also a member of the Admins group. The Admins group must contain at least one user ID there must be a database administrator , and the Admin ID is the default database administrator until you change it.
When you start Access or earlier versions, Access assigns the Admin user ID to you and thus makes you a member of each default group. That ID and those groups Admin and Users give all users full permissions on all the objects in a database — this means that any user can open, view, and change all the objects in all.
One way to implement user-level security in Access or earlier versions is to change the permissions for the Users group and add new administrators to the Admins groups. When you do so, Access automatically assigns new users to the Users group. When you take those steps, users must log in with a password whenever they open the protected database.
However, if you need to implement more specific security — allow one group of users to enter data and another to only read that data, for example — you must create additional users and groups, and grant them specific permissions to some or all of the objects in the database. Implementing that type of user-level security can become a complex task.
To help simplify the process, Access provides the User-Level Security Wizard, which makes it easier to create users and groups in a one-step process. The User-Level Security Wizard helps you to assign permissions and create user and group accounts. User accounts contain user names and unique personal ID numbers PIDs needed to manage a user's permissions to view, use, or change database objects in an Access workgroup. Group accounts are a collection of user accounts that, in turn, reside in a workgroup.
Access uses a group name and PID to identify each work group, and the permissions assigned to a group apply to all users in the group. For more information about using the wizard, see Set user-level security , later in this article. After you complete the wizard, you can manually assign, modify, or remove permissions for user and group accounts in your workgroup for a database and its existing tables, queries, forms, reports, and macros. You can also set the default permissions that Access assigns for any new tables, queries, forms, reports, and macros that you or another user add to a database.
In Access and earlier versions, a workgroup is a group of users in a multiuser environment who share data. A workgroup information file contains the user and group accounts, passwords, and permissions set for each individual user or group of users. You should upgrade or use an alternative browser.

Local time Today, Joined Jan 30, Messages Hi, I've created a duplicate of our database in order to be able to work on the design of it from several locations. Local time Today, Joined Jul 22, Messages 1, Thanks Dennsik, So will I have to have a copy of the mdw along with the db in order to work on it, once I have changed all the user permissions?

Similar threads N. But that is a later question MDA files were kept for backwards compatibility A and still support MDW file workgroup security for databases in the again, backwards compatible MDB format; but databases converted to the newer.
