When disk encryption is enforced, hosts' disk encryption keys will be stored in Fleet.
For macOS hosts that automatically enroll, end users are forced to enable disk encryption during Setup Assistant and the disk encryption key is automatically escrowed to Fleet. For hosts that manually enroll, end users are forced to enable disk encryption. The key gets escrowed the next time they log out and log back in. For both enroll methods, end users can't defer.

For Windows, currently disk encryption is enforced on the C: volume (default system/OS drive) only on hosts with a [TPM chip](https://support.microsoft.com/en-us/topic/what-s-a-trusted-platform-module-tpm-705f241d-025d-4470-80c5-4feeb24fa1ee). For Linux, encryption requires end user interaction.

## Platform SSO
Fleet supports configuring Platform SSO (PSSO) for macOS hosts with the option to create a local user account during enrollment. If you use Okta, see [Deploying Okta Platform SSO with Fleet](https://fleetdm.com/guides/deploying-okta-platform-sso-with-fleet) for setup instructions. PSSO can be used with or without [end user authentication](#end-user-authentication) enabled.
