The U.S. Navy kept something similar but they didn't bother with some things that were beneath notice. For instance, we had a laptop with a Navy "property number" tag. There was a tagged docking station and a tagged monitor. But they didn't bother to track mouse and keyboard because neither of them had any "smarts" - just a USB mouse & keyboard. The mouse and keyboard were "automatic" with the laptop and were treated like staplers and tape dispensers - just another item to keep in the supplies locker.
They had a person table and a tagged item table. If an item was in the warehouse, it had a location code that said Warehouse but it had the owner code of the Navy. If it was checked out to a person, it had a location code that said the office area (open-plan office, so basically room number) and an owner code of the person responsible for it.
Under NO repeat NO circumstances would we have ever kept a password. We used the method that involved a one-way hash of the input password and we merely hashed the offered password to compare hashes. We also did not keep Admin usernames because for Windows that is a fixed string anyway. For security purposes, you never ever IN A GAZILLION YEARS keep a password.
