Passwords

You can set a power-on password, supervisor password, system management password, or NVMe
password in UEFI BIOS to prevent unauthorized access to your computer.
If any of these passwords has been set, a prompt for it will be displayed on the screen whenever the
computer is turned on. The computer does not start until the password is entered.
Note: If only a supervisor password is set, the password prompt will not be displayed when the operating
system is started.

Power-on password

A power-on password protects the system from being turned on by an unauthorized person. The password
must be entered before the operating system can be started. For instructions on how to remove the power-
on password, see "How to remove the power-on password" on page 29.

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)
