How To Recover the root Password in FreeBSD

WP Greet Box icon
Hello there! If you are new here, you might want to subscribe to the RSS feed or subscribe via E-mail for updates on this topic.

The password cannot be recovered. The following procedure will allow you to change the root password.

Do the following:

- when the following boot message appears

Hit [ENTER] to boot immediately, or any other key for command prompt.
Booting [kernel] in 10 seconds...

hit a key, just pick one EXCEPT the ENTER key. You'll get a prompt like:

disk1s1a:>

- type the following commands:

disk1s1a:>unload all
disk1s1a:>load kernel
disk1s1a:>boot -s

The boot process will now start, just wait until it asks you for a shell. Just hit
ENTER and 'sh' will be used as shell.

If you type 'mount' you will see that only your root partition ( / ) is mounted, you will have to mount  'usr' partition as well.

#mount /dev/ad0s1f /usr

Now you have to mount root partition as read-write enabled. Use the following command:

#mount -u /

The root partition should now be mounted read-write. Now you can use 'passwd' program to
change the root password.

#passwd

That's all, reboot the system and login with the new password.
