How to Reset the Administrator Password on Paloalto Firewall

Recovering the administrator password is not possible–the password must be reset using the following procedure

Boot the firewall into maintenance mode and load a previously saved named config.

To boot the firewall into maintenance mode, connect to the console via the console port and a terminal software.

Reboot the firewall and keep pressing ‘m’ (or ‘maint’ for newer versions).

Once you load into maintenance mode, continue to the ‘Select Running Config’ option.

Choose a previous version of the running config for which the administrator password is known and reboot the device with this config.

If a previous config cannot be loaded or the password is unknown for all saved configs, the firewall will need to be factory reset in order to configure a new administrator password.
