Explanation
To track information about devices from which users log in and revoke the device access, the identity architect should use the Activations feature. Activations are records that store information about the devices and browsers that users use to access Salesforce. Administrators can view, manage, and revoke activations for users from the Setup menu. Activations can help monitor and control user access from different devices.
