I cannot log in my Facebook account anymore. This is what I get:
Because you have Login Notifications enabled, you will receive a notification when you log in from a new browser. Please save this browser if you use it often.
I get stuck there. Clicking on "people" only gives a very limited choice for common names. Facebook seems to recognize me but I cannot access my security setting either. Facebook's help department does not answer. What can I do now?
After you click on "Next" a few times, a link saying something like "Do you see this often?" should appear on the page. Click the link. In the popup that appears, click on "Deactivate" to deactivate login notifications. Click logout and login again. This time, you should go straight to your timeline.
It is because you have enabled security check. If Facebook does not recognise the browser from where you login, it asks to save it or not. You can save the browser so that when you login from the same browser on same machine it won't ask you for the confirmation.
