Security Panel

When Security is enabled on a project, users are required to provide a User ID and password to login to that project. Project Security helps teams to collaborate by allowing individuals or groups to intentionally signal that they are working on specific parts of the model.

Available Facilities

The 'Security' panel collects together a set of facilities for managing security in the model, such as enabling Project Security, specifying which security mode to use, defining the lists of authorized users and user groups, and assigning permissions to users and groups to grant access to various aspects of Enterprise Architect's functionality.

This command displays the 'Manage Locks' dialog. The dialog shows a list of all elements and diagrams within the model that have active locks. You can also filter to show only items with User Locks or Group Locks. The list of items can be sorted by lock type, item name, locking user, locking group, or the time of lock application. The dialog can be used to select some or all of the locked items, and then to unlock the selected items.
