The list of usernames is automatically populated with all FileVault Enabled users. If the currently logged-in user is FileVault enabled, that username is chosen by default. Otherwise, the next available FileVault user is selected. If no FileVault-enabled username is entered, an error will be displayed. Please reach out to your administrator for assistance if you receive an error. Key Regeneration: Once you have successfully authenticated, the FileVault Key will be regenerated and may display the key depending on your administrator’s settings, as shown below.
