Command Line access to change Wi-Fi Passphrase

[CyberLake87]

I have managed to change the wifi password for RaspAP and now cannot access the interface. This is not admin/secret pair, this is what was originally ChangeMe.
Can this be altered at the Command Line, I thought I had notes but I cannot find them anywhere,
TIA

Edit hostapd.conf with sudo nano /etc/hostapd/hostapd.conf and set the wpa_passphrase value.
Give the service a kick for the changes to take effect: sudo systemctl restart hostapd.service.
