Actually no.... A WPA2 pre-shared key is 256bits, 64 hexadecimal characters. 
Most manufactures allow you to enter an 8+ character passphrase, which is 
then hashed using a common function into a 64 hex character shared key.... 
Most in the general population can not accurately copy a 20 digit license key 
for their software, let alone 64 digits for the WPA into 2 or more devices. 
It is the 8-12 character passphrases which can be easily dictionary 
matched... not the 64 character key.
