: On a desktop browser, you can sometimes access the Facebook People Directory at the bottom of the login page. This lets you search for names to confirm if an account exists, though it won't show you the full profile.
: Sites like Social Searcher or PeekViewer aggregate publicly available data. They don't "hack" into private accounts but rather scrape what is already visible to the public in a cleaner interface.
: You can find public profiles by searching site:facebook.com "Person's Name" . This allows you to view what search engines have indexed without actually logging into the platform.
