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.
