I thought we would start off with how to do a password reset in pfSense. I have come across this several times when either taking over a firewall or I just plain forgot it. Either way, you need a console cable to get into CLI to do this. Below is how it looked. Its pretty simple, you select "3", then "y", then you are done.
FreeBSD/arm (FW.localdomain) (ttyu0)
Netgate SG-3100 - Serial: XXXXXXXX - Netgate Device ID:
*** Welcome to pfSense 2.4.5-RELEASE-p1 (arm) on FW ***
WAN (wan) -> mvneta2 -> v4/DHCP4: 220.127.116.11/23
LAN (lan) -> mvneta1 -> v4: 192.168.168.1/24
OPT1 (opt1) -> mvneta0 ->
0) Logout (SSH only) 9) pfTop
1) Assign Interfaces 10) Filter Logs
2) Set interface(s) IP address 11) Restart webConfigurator
3) Reset webConfigurator password 12) PHP shell + pfSense tools
4) Reset to factory defaults 13) Update from console
5) Reboot system 14) Disable Secure Shell (sshd)
6) Halt system 15) Restore recent configuration
7) Ping host 16) Restart PHP-FPM
Enter an option: 3
The webConfigurator admin password and privileges will be reset to the default (which is "pfsense").
Do you want to proceed [y|n]? y
The password for the webConfigurator has been reset and
the default username has been set to "admin".
Remember to set the password to something else than
the default as soon as you have logged into the webConfigurator.
Press ENTER to continue.
