See About the creator's account and Default account (Claris Pro only) or About the Admin and Guest accounts (FileMaker Pro only). Each file also contains two predefined accounts. You can grant account access to as many users or groups as you need. However, after the clients close the file, they won't be able to open it again. For example, if you make an account access entry inactive while clients are using it, their usage of the file is not interrupted. The account access changes you make take effect immediately but do not disrupt any current clients. You can create and modify account access in a shared file while clients are using it. If you open the file without full access privileges, the File menu > Manage > Security command lets you change fewer options or the command is disabled. To fully manage account access for a file, you must open the file as a user whose account access entry is assigned the Full Access privilege set. See About accounts, privilege sets, and extended privileges. When a user opens a file with correct account information, the privilege set assigned to the account access entry in the file for that user's account, or for the group that user is in, determines what the user can do in that file. When a user opens a file, a dialog box usually prompts the user to enter account information.

For some types of accounts (see below), groups of users can be defined. Account access entries in a file specify user names (and for FileMaker file accounts, passwords), which identify users.
