How can I get the facebook mobile login?

Not much code needed, really. I mean, you can just cut and paste the URL, change to your app id and redirect URL and paste it in your browser. Then do check the same URL on your iphone. Go to your Account Settings page and select the Change option next to AccountSecurity. Check the box under LoginApprovals. If you don’t have a mobilephone number linked to your Face book account, you will need to add one. Followthe steps provided when you check the box to turn on Login Approvals or learnmore. If you are haven't named the device you are on, you will be prompted todo so when you turn on Login Approvals. Do not click the "Save thisdevice" option if you are using a public device. Note that all of thedevices linked to your Face book account are listed under the Login Approvals section.
