As long as Fleetsmith is the source to encrypt a device, a FileVault 2 Recovery Key will be available in the Fleetsmith web app.
To view an escrowed Recovery Key:
1. In the Fleetsmith web app, click "Devices".
2. Click the Computer name of the device you need the Recovery Key for.
3. On the individual device's Overview page, scroll down to the "Health" area.
4. Click "Show Key". (This option will be available as long as Fleetsmith encrypted the device. If the device was encrypted prior to Fleetsmith, you will only see "Managed".)
You can also view a device's Recovery Key on a device's "Details" page under "Security" towards the bottom of the page.
