Facebook Privacy Settings Guide: How to Lock Down Your Profile in 2026

Facebook remains the world's largest social network with nearly 3 billion monthly active users. By default, much of your personal information — profile photos, friend lists, likes, and even your location history — is visible to the public. This data is a goldmine for scammers, stalkers, and data brokers.

Why Social Media Privacy Matters

• Social engineering: Public information is combined for phishing attacks
• Identity theft: Photos and data are used to create fake accounts
• Stalking: Location check-ins and daily routines become visible
• Employment risk: Employers routinely review social media profiles

Sharing Personal Information Safely

When you need to share your phone number, address, or bank details through Messenger or Instagram DMs, remember that these messages are stored on Meta's servers. Messenger does not use end-to-end encryption by default.

LOCK.PUB lets you create password-protected, auto-expiring memos. Instead of sending sensitive data through iMessage or Messenger, share a secure link that self-destructs after reading.

Checking for Data Breaches

• Have I Been Pwned (haveibeenpwned.com): Check if your email has been compromised
• Facebook settings: Download your data to see exactly what Facebook has collected

FAQ

Q: If I make my Instagram private, what happens to existing followers? A: Existing followers stay. Only new followers require your approval.

Q: Are Messenger conversations encrypted? A: Not by default. You need to start a "Secret Conversation" for end-to-end encryption.

Q: Can employers see my Facebook posts? A: If your posts are public, yes. Set your default audience to "Friends only."
