A password-secured hard drive stays locked even when removed from the computer or placed into another computer. It prevents an attacker from accessing data on the drive without authorization. The following rules and dependencies apply when the M.2 PCIe SSD-0 password is used - The M.2 PCIe SSD-0 password option cannot be accessed when a drive is disabled in the BIOS setup. The computer shuts down when idle for approximately 10 minutes at the solid-state drive password prompt. The computer shuts down after three incorrect attempts to enter the solid-state drive password and treats the drive as not available. The solid-state drive does not accept password unlock attempts after five incorrect attempts to enter the drive password from the BIOS Setup. The solid-state drive password must be reset for the new password unlock attempts. The computer treats the solid-state drive as not available when the Esc key is pressed at the drive password prompt. The solid-state drive password is not prompted when the computer resumes from standby mode. When the solid-state drive is unlocked by the user before the computer goes into standby mode, it remains unlocked after the computer resumes from standby mode. If the computer and solid-state drive passwords are set to the same value, the drive unlocks after the correct computer password is entered. Dell Technologies recommends using a solid-state drive password to protect unauthorized data access.
Owner Password	The Owner Password is typically used when a computer is loaned or leased, and the end user sets their own computer or hard drive password. The Owner Password can provide override access to unlock the computer when it is returned. The Owner Password cannot be set using BIOS Setup. System lessors are given a tool which enables them to configure the Owner Password. The following rules and dependencies apply when the Owner Password is used - The owner password cannot be set when the administrator password is already set. The owner password can be used in place of the administrator, computer, or hard drive passwords. NOTE:The solid-state drive password must have been set on the computer with the owner password. Dell Technologies recommends that only computer lessors use the owner password.
Strong Password	The Strong Password feature enforces stricter rules for administrator, owner, and computer passwords. When enabled, the following rules are enforced - The minimum length of the password is set to eight characters. The password is required to include at least one upper case and one lower case character. NOTE:These requirements do not affect the drive password. By default, the Strong Password option is enabled. For additional security, Dell Technologies recommends keeping the Strong Password option enabled as it requires passwords to be more complex.
Password Configuration	The Password configuration page includes several options for changing the requirements of BIOS passwords. You can modify the minimum and maximum length of the passwords and require passwords to contain certain character classes (upper case, lower case, digit, special character). Dell Technologies recommends setting the minimum password length to at least eight characters.
Password Bypass	The Password Bypass option allows the computer to reboot from the operating system without entering the computer or hard drive password. If the computer has already booted to the operating system, it is presumed that the user has already entered the correct computer or hard drive password. NOTE:This option does not remove the requirement to enter the password after shutting down. By default, the Password Bypass option is disabled. For additional security, Dell Technologies recommends keeping the Password Bypass option disabled.
Password Changes

NOTE:This option is not available when the virtualization setting for IOMMU is disabled (VT-d/AMD Vi). By default, the Enable OS Kernel DMA Support option is disabled. NOTE:This option is provided only for compatibility purposes, since some older hardware is not DMA capable.
