## What are the implications of using the sleep or hibernate power management options? ## What are the implications of using the sleep or hibernate power management options?
BitLocker on operating system drives in its basic configuration (with a TPM but without additional startup authentication) provides additional security for the hibernate mode. However, BitLocker provides greater security when it is configured to use an additional startup authentication factor (TPM+PIN, TPM+USB, or TPM+PIN+USB) with the hibernate mode. This method is more secure because returning from hibernation requires authentication. For improved security, we recommend that sleep mode be disabled and that you use TPM+PIN for the authentication method. Startup authentication can be configured by using [Group Policy](./bitlocker-group-policy-settings.md#a-href-idbkmk-unlockpol1arequire-additional-authentication-at-startup) or Mobile Device Management with the [Bitlocker CSP](/windows/client-management/mdm/bitlocker-csp).
