Tips:
-Some e-mail accounts call for an added action to import your Contacts right into Facebook. Gmail Contacts, for instance, have to be exported to a CSV data and published to Facebook. The Find Friends wizard will provide on-screen instructions if you should take added steps.
-Facebook states that it does not keep your e-mail password. It is only used to access your account in order to import your Contacts into Facebook.
