Deployment

For initial deployment of Escrow Buddy, Kandji administrators can follow this template:

Library Item: FileVault

Ensure the Escrow Recovery Keys to Kandji option is enabled. See this KB article for details.

NOTE: Enabling this option will present a FileVault Recovery Key "action" in the Kandji menu item. Users can either log out and let Escrow Buddy generate a new key silently upon next login, or they can follow the prompt in the Kandji menu to generate a new key by providing their password. Either way, the result will be the same: the new key will be escrowed to Kandji.
