+Title: Resetting passwords in single-user mode on OpenBSD
+Author: Alex Arch <aa@manpager.org>
+Created: 2025-03-08
+Modified: 2025-03-08
+
+Recently I've been careless with my password management, and lost
+passwords for my openbsd.amsterdam VM. Thankfully, the system is pretty
+DIY, and I was able to reset them by running the VM in single user mode.
+
+It's pretty simple to do, really. Here's how.
+
+The below commands are only really specific to openbsd.amsterdam up
+until the boot prompt. After that it's the same so long as you have a
+physical (in my case a "physical" serial) connection to the machine.
+
+$ ssh myuser@serverXX.openbsd.amsterdam
+$ vmctl status | awk '$7 == "myuser" {print $9}'
+vmX
+$ vmctl stop -w vmX && vmctl start -c vmX
+
+Wait a bit, and you should get the boot prompt (">"). Quickly type
+"boot -s":
+
+> boot -s
+
+Prompted for the path to shell, either just press enter, or type
+/bin/ksh if you need that.
+
+Enter pathname of shell or RETURN for sh: /bin/ksh
+
+Finally, you can customise your input.
+
+# kbd us.dvorak
+# set -o vi
+
+Remount the root partition as read-write, and mount the /usr partition
+(you'll need passwd(1), which is in /usr/bin/passwd).
+
+# mount -uw /
+# mount -w /usr
+
+If that doesn't work, you might find 'sysctl hw.disknames' and
+disklabel(8) to be helpful.
+
+Regardless, after mounting the necessary partitions, you should be able
+to reset the passwords and reboot.
+
+# passwd root
+# passwd myuser
+# reboot
+
+If you are on a serial console like me, press ~. (tilde dot), possibly
+preceeded by Return (Enter) to disconnect.
