Users who registered using the Facebook connect feature do not have a password
Users who registered via Facebook cannot log in using their email + password unless they set up a password afterwards by going through their profile settings
Users connecting from a mobile device, a different computer, or who currently do not wish or do not have access to Facebook cannot log in into the forum.
Current work around:
Users can currently manually go to their profiles and set up a password, and they''ll be able to log in using email+password. I found this to be rather counter intuitive for a lot of lest technologically inclined people (the members I will be targeting with my board).
Adding a password step to the registration process when using Facebook connect to register would allow users to log in using email+password from any device
