title: Do I need a password for users who login via Facebook?
body: <p>I have a website that allows a person to create an account with username/password. Once its created they can login and add their own content. Im now thinking about allowing them to login via their facebook profile, so when they go to my login there will be a button that says login with facebook. Then a window will popup to give permission to my facebook app so I can get their info. Once I do that do I need them to create a password still? Or once they initially give permission for their account I dont need a password, so when they come back to the site they just need to reconnect to their facebook profile? Hope this makes sense.</p>
