I have separated the login integration I had within WPHPBB. For those of you who didn’t want to completely replace your comment system but would like to integrate your WordPress and phpBB logins, this might do the trick.
This does not directly modify your databases.

What the plugin actually does:
Redirects users to a login page which verifies the users login information with phpBB and logs them into WordPress accordingly. If the user doesnt exist in WP, then the user is created given the default role and logged in. If the users email or password changes (through phpBB), then the information is updated in WordPress.
