[Semibug] OpenBSD - Authenticate boot into single user mode

[Jonathan Drews]

Hi People:

  I have an OpneBSD laptop. I was distrurbed to find this:

I Forgot My Root Password
https://www.openbsd.org/faq/faq8.html

You boot into single user mode;
boot> boot -s

and now have root privliges and can change the root password!

My question is how do I prevent this? I thought of using a BIOS
level password. That would suspend the boot process until you
entered a password. However the thief could remove the CMOS battery
and the BIOS would reset.

How can I require authentcation on single user mode boot in OpenBSD?


Kind regards,

Jonathan
