i use open graph for access member to register and login with facebook account in codeigniter, and i have idea to create automatic password with access token for every user, but i dont exactly know is it access token facebook is static or will different every time user access with other IP or something?
Thankyou
分享 The access token is valid for 2 months (if you request an extended token, otherwise only a few hours). It will remain the same until the user deletes the app from his/her account or changes his/her password. Then you need to re-authenticate by sending the user to FB again through your app.
IP address does not matter.
