Updated: 2026-Jan-16

Starting from BioStar 2 v2.9.11 and BioStar X v1.0.0, the Master Admin and 2 Step Authentication features are supported.

⚠️ Important:
These features are directly related to firmware downgrade restrictions. Once enabled, firmware downgrade may no longer be available.
Please carefully review this limitation before upgrading the firmware on existing devices or purchasing new devices with the latest firmware pre-installed.

Mandatory Requirements and Precautions

If you are using CE-marked devices with the firmware versions listed below (or later) that support the Master Admin feature , you MUST thoroughly review the document linked above in advance.

• Note: This requirement applies only to CE-marked products running the firmware versions specified below.

⚠️ Critical for CE-marked Devices:
For CE-marked devices running the firmware versions listed below (or later), Master Admin MUST be configured on the device before the initial installation and deployment to access the device menu. Failure to do so may result in restricted administrative access.

⚠️ Administrator Authentication Policy (Mandatory):
For CE-marked devices running the firmware versions listed below (or later), the following administrator authentication policy applies. Not only for the Master Administrators, but also for ALL device administrator accounts (All / User / Config) are required to use 2 Step Authentication as designed.

• Each administrator MUST register and use at least two different credential types (e.g., Card and PIN).

• Single-factor authentication for administrator accounts is NOT supported under this security model.

• "ID + PIN" is NOT available for any device administrators as this credential is regarded as a singel-factor authentication on the Suprema design.

* The requirements described above apply only to CE-marked products running the firmware versions listed in this table (or later). Devices not listed in the table will be added as support becomes available in future firmware releases.
