# Product updates

The Hideez Authentication Service update should be carried out comprehensively, including:

* [HES server](/product-updates/product-updates.md#how-to-update-hes-server);
* [Hideez Client applications on all workstations](/product-updates/product-updates.md#how-to-update-hideez-client);
* [Firmware in Hideez Key devices](/product-updates/product-updates.md#how-to-update-firmware);
* [Hideez Authenticator](#how-to-update-the-hideez-authenticator).

Updating the firmware, client and server can be done in any order, the main thing is that finally, all versions match.

### How to update the HES server

You can find guides on HES update [*here*](/product-updates/hideez-enterprise-server-updates.md).

### How to update the Hideez Client

Update Hideez Client by installing a new version over the old one. This is a standard procedure that can be performed by installing through the GPO (Group Policy Object). When updating, the application settings are saved.

You can find the latest stable version of Hideez Client [*here*](/product-updates/hideez-client-updates.md).

### How to update the firmware

Hideez Maintenance application is used to update the firmware, detailed instruction is [*here*](/hideez-key-enterprise-edition/updating-firmware.md). 

You can find the latest stable version of firmware [*here*](/product-updates/hideez-key-firmware-updates.md).

When updating the firmware, the data is saved, although when updating very old firmware versions, the data may be lost, because when adding new functionality (for example, FIDO authorization system) we are forced to redistribute the internal memory of the device. Please consult Hideez Technical Support before upgrading.

### How to update the Hideez Authenticator

You can find the latest stable version of Hideez Authenticator [*here*](/product-updates/hideez-authenticator-updates.md).
