Password reset
|
||
|
|
====================================
|
||
|
|
|
||
|
|
Sometimes people lose their passwords, in which case it can be practical to reset the root password
|
||
|
|
without performing a reinstall.
|
||
|
|
|
||
|
|
This guide describes step by step how to reset the root password.
|
||
|
|
|
||
|
|
.. Note::
|
||
|
|
|
||
|
|
You can also use the installer to reset the password,
|
||
|
|
use the :code:`Password Reset - Recover Installation` option in the installer after the keymap selection.
|
||
|
|
|
||
|
|
|
||
|
|
-----------------------------
|
||
|
|
Step 1 : power
|
||
|
|
-----------------------------
|
||
|
|
|
||
|
|
Since you need to influence the boot process to reset the password, you should start with powering off the (virtual) device.
|
||
|
|
|
||
|
|
-----------------------------
|
||
|
|
Step 2 : console
|
||
|
|
-----------------------------
|
||
|
|
|
||
|
|
Make sure you are able to access the (virtual) console, in case it's a physical machine you might want to connect a
|
||
|
|
monitor and keyboard, when it's an appliance with serial access, make sure to connect to the serial/usb port using an application
|
||
|
|
like putty.
|
||
|
|
|
||
|
|
.. Tip::
|
||
|
|
|
||
|
|
When using devices from the OPNsense shop (https://shop.opnsense.com), usually there's a mini-usb to serial cable included
|
||
|
|
in the box, the :doc:`Serial Console connectivity </hardware/serial_connectivity>` guide will help you with the setup.
|
||
|
|
|
||
|
|
-----------------------------
|
||
|
|
Step 3 : boot single
|
||
|
|
-----------------------------
|
||
|
|
|
||
|
|
Swith the power and wait for the OPNsense splash screen to appear, the choose "Boot [S]single User" which should be option 2 in the list.
|
||
|
|
(press 2)
|
||
|
|
|
||
|
|
-----------------------------
|
||
|
|
Step 4: password reset
|
||
|
|
-----------------------------
|
||
|
|
|
||
|
|
This stage depends on the type of installation, the root filesystem could either be UFS or ZFS, both requiring different commands to
|
||
|
|
enable modifications in single user mode.
|
||
|
|
|
||
|
|
|
||
|
|
For UFS file systems, execute the following command in the shell to enable disk modifications:
|
||
|
|
|
||
|
|
.. code-block:: sh
|
||
|
|
|
||
|
|
/sbin/mount -o rw /
|
||
|
|
|
||
|
|
|
||
|
|
When using ZFS, the following commands are required
|
||
|
|
|
||
|
|
.. code-block:: sh
|
||
|
|
|
||
|
|
/sbin/mount -u /
|
||
|
|
/sbin/zfs mount -a
|
||
|
|
|
||
|
|
Now the disk can be written to, use the following commands to reset the password and reboot the machine:
|
||
|
|
|
||
|
|
.. code-block:: sh
|
||
|
|
|
||
|
|
opnsense-shell password
|
||
|
|
reboot
|
||
|
|
|
||
|
|
The `opnsense-shell` will ask for a confirmation, respond with `Y`
