## How it works ## How it works
The solution uses Dell's native WMI security interface (`root\dcim\sysman\wmisecurity`), specifically the `PasswordObject` and `SecurityInterface` WMI classes. These are exposed directly by Dell UEFI firmware via Windows' built-in ACPI WMI bridge driver (`wmiacpi.sys`) — **no Dell Command | Monitor or Dell Command | Update installation is needed**.

Inside the container, upload two Base64-encoded `.txt` files:
- `current-content.txt` — the current BIOS Admin password (Base64 encoded) - `current-content.txt` - the current BIOS Admin password (Base64 encoded)
- `old-content.txt` — all known previous passwords, one per line (Base64 encoded), plus one blank line to handle devices with no BIOS password currently set - `old-content.txt` - all known previous passwords, one per line (Base64 encoded), plus one blank line to handle devices with no BIOS password currently set
As passwords change over the years, update both files in the storage account accordingly. As passwords change over the years, update both files in the storage account accordingly.
