01 ACCOUNT PROTECTION
Use the ‘Security and login’ section to lock your account and so prevent unwanted intrusion.
02 GET UNFRIENDLY

See what friends are posting about you by activating ‘tag reviewing’ under the ‘Timeline and tagging’ option.
04 BLOCK AND MUTE
Remove every nuisance, from troublesome friends to annoying app requests, in the Blocking section.
