Possible to log into facebook using username/password instead of Client UI?

Is there a way for me开发者_运维百科 to use my username/password to get my Facebook authentication token instead of using the facebook UI? I'd like to do it without any user interaction...

No, this is not possible (and is prohibited). You can however use the UI to get an access token and request the offline_access permissions. This permission will give you a token that does not expire which you can use to do what you are attempting to do without user interaction.
