The OTR protocol still uses proper authentication, it's just that the
messages aren't signed, thus allowing the user to deny creating the message
if needed. However, for an OTR session to begin, you must authenticate that
the person you are speaking is with, is the one you wish to communicate.
This is handled through the socialist millionaires protocol, and every OTR
client should have SMP properly developed.
