How to reset root password on OpenBSD

tags: openbsd, tips

If you forgot root password and have a phisical access to console, you can easily reset it.

Reboot your computer with [Ctrl]+[Alt]+[Del]

At the boot prompt enter:

boot -s

It boots OpenBSD in the single-user mode.

The root filesystem is mounted read-only in this case.

To re-mount it as ‘read-write’ run:

mount -uw /

Change password with passwd and reboot the system.
