Where can I find documentation that recommends not using a passphrase? 
My understanding is a passphrase is important to protect private keys in 
the event they are acquired: 
http://www.gnupg.org/gph/en/manual/c481.html#AEN506

If I don't use a passphrase, how should I protect my key (other than 
making it difficult to physically access)?

Cheers,
