How to Lock Down Your Social Media Privacy Settings

Social media can help you stay connected, share updates, build relationships, and express yourself. But the same information you share with friends can also be used by scammers, identity thieves, impersonators, and people trying to guess security answers.

Locking down your privacy settings does not mean disappearing online. It means choosing who can see your information, who can contact you, and what personal details are available to strangers.

In this guide, you’ll learn how to review your social media privacy settings and reduce the information others can use to target or impersonate you.

TL;DR: Quick Decision Guide

• If your profiles are public → review what strangers can see.
• If your birthday, phone number, email, or location is visible → hide or limit it.
• If anyone can message or tag you → tighten contact and tagging settings.
• If your friends list is public → make it private when possible.
• If old posts reveal too much → limit past posts or archive them.

Step 1: Review What Strangers Can See

Start by looking at your profile as if you were a stranger. Many platforms let you “view as public” or see what non-friends can view.

Scammers can use public details to personalize scams, impersonate you, answer security questions, or target your family. CISA recommends keeping Social Security numbers, account numbers, passwords, full names, addresses, birthdays, and vacation plans private on social media.

What to do:
Check your public profile for:

• Full birthday
• Phone number
• Email address
• Home address or neighborhood
• Workplace or school
• Family relationships
• Children’s school or activities
• Travel plans
• Photos of IDs, tickets, bills, or documents

Remove, hide, or limit anything that gives strangers too much information.

Smile Money Tip: Privacy settings are not about hiding your life. They are about deciding who gets access to the details of your life.

Step 2: Limit Who Can Contact You

Many scams begin with a message, friend request, tag, or comment from someone you do not know.

Review who can:

• Send you friend or follow requests
• Send direct messages
• Comment on your posts
• Tag you in photos or posts
• Mention you in comments
• Add you to groups
• See your active status
• Find you by email or phone number

CISA’s social media security guidance recommends updating privacy and security settings to your comfort level and being careful about what you share publicly.

What to do:
Set contact permissions to friends, followers you approve, or people you know when possible. Turn on tag review so posts do not appear on your profile without your approval.

Step 3: Hide Personal Details That Can Be Used Against You

Some personal details feel harmless, but they can help scammers build trust or guess security questions.

Be careful with:

• Mother’s maiden name
• First pet
• Childhood street
• Hometown
• High school
• Full birthdate
• Family member names
• Phone number
• Email address
• Location check-ins
• Vacation countdowns

These details can show up in security questions, password guesses, phishing messages, or impersonation scams.

What to do:
Remove sensitive profile fields or set them to “only me.” Avoid public posts that reveal when you are away from home, where your children go to school, or which relatives might be vulnerable to emergency scams.

Step 4: Review Old Posts, Photos, and Tags

Old posts can reveal information you would not share today. Photos may show your house number, license plate, workplace badge, school logo, travel documents, boarding passes, or financial papers in the background.

What to do:

• Limit the audience for old posts.
• Archive posts that reveal too much.
• Remove tags from posts you do not want connected to your profile.
• Delete photos showing IDs, tickets, checks, documents, or location clues.
• Review public albums, highlights, reels, and stories.
• Turn off location tagging or geotagging.

This is especially useful before travel, after moving, after a breakup, during job searches, or when caring for older family members.

Step 5: Secure the Account Itself

Privacy settings control what people see. Security settings control who can get in.

Protect each social account with:

• A strong, unique password
• Two-factor authentication
• Updated recovery email and phone number
• Login alerts
• Review of connected apps
• Removal of unfamiliar devices
• Caution with suspicious links and DMs

CISA recommends connecting only with people you trust, protecting passwords, and using multi-factor authentication as part of social media cybersecurity.

What to do:
Start with the social platform you use most. Change reused passwords, turn on two-factor authentication, and check recent login activity.

Common Mistakes to Avoid

• Keeping profiles fully public by default
• Sharing real-time travel or location details
• Leaving your friends list visible to everyone
• Accepting requests from people you do not know
• Ignoring tags from other people
• Using the same password across social and email accounts

What to Do If Someone Impersonates You

If someone creates a fake profile using your name or photos:

• Take screenshots of the fake profile.
• Report the account to the platform.
• Tell friends not to accept requests or send money.
• Tighten your privacy settings.
• Search for other fake profiles using your name or photos.
• Report fraud to the FTC if the impersonator is scamming people.

If your actual account was hacked, change your password, turn on two-factor authentication, remove unknown devices, and review messages sent from your account.

Final Thought

Social media privacy is not one setting. It is a set of choices about visibility, contact, tagging, location, and account security.

Start with what strangers can see, then tighten who can contact you and how your account is protected.
