The owner of the machine is the owner of the secure boot keys.
J4k3, hope youre doing alright dude.
Got a question you may be able to help me with. I have never changed my secure boot key on my motherboard after switching from windows. Do I need to worry about anything? If I don't, what's the pros and cons and what not.
I remember reading that there's some sort of potential issues with keys from windows if you're a Linux user a few months back.
I remember reading a post on mastodon where it was explained that no mother board validates the secure boot keys expiration dates otherwise it wouldn't boot the first time the BIOS battery gets empty and the internal clock gets reset. The post was written well and was citing some sources. But I didn't try to verify these assertions.
even if it did, its not like any existing motherboard requires internet to boot, you can just change the MB clock to be prior to the expiration and theoretically it should boot regardless of restrictions.
