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.

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. Personal Messenger chats are now end-to-end encrypted by default, but business and Marketplace chats are not.
LOCK.PUB lets you create password-protected memos, and with Pro you can set them to expire or open only once. Instead of sending sensitive data through iMessage or Messenger, share a secure link that can't be opened again after it's read — try one free on the One-Time Secret page.
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: Personal chats are end-to-end encrypted by default, so you no longer need to start a "Secret Conversation." Business and Marketplace chats are the exceptions.
Q: Can employers see my Facebook posts? A: If your posts are public, yes. Set your default audience to "Friends only."
Take Action Today
Social media privacy settings take just 15 minutes to configure but provide lasting protection. Review your settings today, and when you need to share sensitive information, use LOCK.PUB for encrypted messages that can't be reopened once read.
