Yes, but that is generally not a good idea at a colo, unless you have some
kind of physical security on the box.

FYI: secure single password mode is default: meaning that the system assumes
that anyone that can physically access the system should be able to use
single user mode without a password.

You have to make changes to /etc/ttys to get a paranoid console that asks for
a password.

Linux, Linux, Linux.

FreeBSD has no /etc/shadow.  There's /etc/passwd and /etc/master.passwd.

The password hash is readible by root only, so that doesn't help if you
only have a mortal account.

Unless you've specifically set up something else to work around this
problem, you _must_ get physical access to fix it.

In the future, try installing sudo or using PKI to protect yourself from
lost passwords.
