So I just made a raspberry pi PirateBox I wanted to know how do you password protect a raspberry pi pirate box??

try adding

auth_algs=1           # 1=wpa, 2=wep, 3=both
wpa=2                 # WPA2 only
wpa_key_mgmt=WPA-PSK 
rsn_pairwise=CCMP
wpa_passphrase=somepassword

to /opt/piratebox/conf/hostapd.conf
