Nvme Passwords; Supervisor Password; System Management Password - Lenovo ThinkPad L13 Yoga Gen 4 Hardware Maintenance Manual

NVMe passwords

The NVMe password prevents unauthorized access to the data on the storage drive. When an NVMe
password is set, you are prompted to type a correct password each time you try to access the storage drive.
• Single Password
When a Single NVMe password is set, the user must enter the user NVMe password to access files and
applications on the storage drive.
• Dual Password (User + Admin)
The admin NVMe password is set and used by a system administrator. It enables the administrator to
access any storage drive in a system or any computer connected in the same network. The administrator
can also assign a user NVMe password for each computer in the network. The user of the computer can
change the user NVMe password as desired, but only the administrator can remove the user NVMe
password.
When prompted to enter an NVMe password, press F1 to switch between the admin NVMe password and
user NVMe password.
Notes: The NVMe password is not available in the following situations:
• A Trusted Computing Group (TCG) Opal-compliant storage drive and a TCG Opal management software
program are installed in the computer, and the TCG Opal management software program is activated.
• For Intel models, when an eDrive storage drive is installed in the computer preinstalled with the Windows
10 operating system.

Supervisor password

The supervisor password protects the system information stored in UEFI BIOS. It provides the following
security features:
• If only a supervisor password is set, a password prompt is displayed when you try to enter the UEFI BIOS
menu. Unauthorized users cannot change most of the system configuration options in the UEFI BIOS
menu without the password.
• The system administrator can use the supervisor password to access a computer even if the user of that
computer has set a power-on password. The supervisor password overrides the power-on password.
• The system administrator can set the same supervisor password on many ThinkPad notebook computers
to make administration easier.
Attention: If the supervisor password has been forgotten and cannot be made available to the service
technician, there is no service procedure to reset the password. The system board must be replaced for a
scheduled fee.

System management password

The system management password can also protect the system information stored in UEFI BIOS like a
supervisor password, but it has lower authority by default. The system management password can be set
through the UEFI BIOS menu or through Windows Management Instrumentation (WMI) with the Lenovo
client-management interface.
You can enable the system management password to have the same authority as the supervisor password
to control security related features. To customize the authority of the system management password through
the UEFI BIOS menu:
1. Enter the UEFI BIOS menu.
