Securing BIOS Passwords in Unattended Deployments

My Dell, HP, and Lenovo BIOS password and settings scripts all accept the BIOS password as a plain-text parameter. This keeps the scripts simple and broadly compatible, but it means that how you deliver the password to the script is also how you secure the password. This post covers how to do that safely under Configuration Manager and task sequences, and how the built-in CMS support added in version 2.3.0 makes it easier. ...

HP BIOS Password Management (HPCMSL)

This post covers script version 2.3.0. This is the HP Client Management Script Library (HPCMSL) variant of my HP BIOS password management script. It performs the same task as the WMI-based variant - automatically setting, changing, or clearing the Setup and Power-On passwords with logging and optional user prompts - but it uses the HPCMSL cmdlets instead of talking to the HP WMI interface directly. If you would rather avoid the module dependency, see the WMI variant. ...

HP BIOS Settings Management (HPCMSL)

This post covers script version 2.3.0. This is the HP Client Management Script Library (HPCMSL) variant of my HP BIOS settings management script. It performs the same task as the WMI-based variant - getting a list of current BIOS settings and setting BIOS settings from either the body of the script or a CSV file - but it uses the HPCMSL cmdlets instead of talking to the HP WMI interface directly. If you would rather avoid the module dependency, see the WMI variant. ...

HP BIOS Settings Management

This post was updated on May 25th, 2026 and covers script version 2.3.0. This script is now available in two variants. This post covers the WMI-based variant (Manage-HPBiosSettings-WMI.ps1), which talks directly to the HP WMI interface and has no module dependencies. There is also a variant built on the HP Client Management Script Library: HP BIOS Settings Management (HPCMSL). This post is one of 3 posts in my series on managing BIOS settings using PowerShell. I’ve also written about Dell and Lenovo. In this post I’ll be talking about using PowerShell to manage HP BIOS settings. ...

HP BIOS Password Management

This post was updated on May 25th, 2026 and covers script version 2.3.0. This script is now available in two variants. This post covers the WMI-based variant (Manage-HPBiosPasswords-WMI.ps1), which talks directly to the HP WMI interface and has no module dependencies. There is also a variant built on the HP Client Management Script Library: HP BIOS Password Management (HPCMSL). In my last blog post, (Lenovo BIOS Password Management), I talked about managing Lenovo BIOS passwords with PowerShell. I liked how that process worked, so I decided to create a similar process to handle HP BIOS passwords. Once again, the goal was to have a script that could automatically set, change, or clear BIOS passwords while providing logging and optional user prompts. In this post, I’ll cover the basics of how the script works and some limitations of the script. ...
