MyBB is nice and easy to use. But does not have better security than Vbulletin, nothing is encrypted as it gets sent in for a user login session. Vbulletin sends the %pass% variable in as an MD5 hashed version of the plain text, and MyBB doesn't. Maybe future MyBB versions will do this, but right now they don't.
