There's a little-known secret about the Facebook social network: You can look at Facebook profiles, pages, apps and places without ever signing into an account. At least, you can view everything that is public and that users have not restricted via the site's advanced privacy settings. But a large portion of user profiles are accessible from Facebook's People Search feature, and you might find what you're looking for.
Go to "facebook.com/people-search.php" in your browser.
Type the first and last name for the person you want to search for. If you don't know who you are searching for, you can browse public listings instead.
Click on any of the letters under the "Browse by Name" section. It will take you to a directory page showing listings for that letter. You can further navigate to any other section by clicking on a new letter or clicking the "People," "Pages," "Apps" or "Places" tabs.
Click on the name you want to view. You can see all the public information that person is willing to share. In some cases, Facebook users do not know they are sharing so much information publicly.
