How to Reduce Daily Privacy Risks on Social Media

Social media is where most people accidentally leak the most personal information. You do not need to delete your accounts to stay safer — you need a handful of consistent habits and a few minutes in each platform's settings. This guide covers practical, repeatable steps you can take today on the platforms US users rely on most.
Start With Account Visibility
The fastest win is controlling who can see your content. On Instagram and TikTok, switch to a private account so only approved followers see your posts. On Facebook, use the audience selector (the icon next to each post) to choose "Friends" instead of "Public," and set your default audience to "Friends" in your privacy settings. On X (Twitter), protect your posts so they are visible only to approved followers.
A private account does two things at once: it limits what strangers and data-scraping tools can collect, and it reduces your exposure to targeted scams that rely on knowing your routine, employer, or family.
Limit the Personal Details You Publish
Cybercriminals and identity thieves look for the same details you might hand out casually:
- Your full birth date — used for account recovery and identity checks. Use a month and day, keep the year private, or enter a substitute if a platform requires a value.
- Your phone number — a common target for SIM-swap and phishing. Where the platform allows, log in with your email instead, and do not list your number publicly on your profile.
- Your home address and real-time location — avoid tagging your home, and consider waiting until after a trip to post photos from it.
- Your employer, schedule, and travel plans — useful to burglars and scammers who build a profile of you over time.
Turn On Two-Factor Authentication
Every major platform supports two-factor authentication (2FA). Enable it everywhere you can, and prefer an authenticator app or a hardware security key over SMS, which is vulnerable to SIM-swap attacks. With 2FA on, a stolen password is usually not enough for someone to take over your account.
Audit Third-Party Apps and Quizzes
"Log in with Facebook/Google" buttons are convenient, but every quiz, game, and productivity tool you connect can request access to your profile and sometimes your friends' data. Go to your account's Apps and Websites (or "Connected apps") settings at least twice a year and remove anything you no longer use. Only reconnect tools from developers you recognize and trust.
Personality quizzes and "find out which character you are" apps are a classic data-harvesting vector. If a quiz asks for access to your account to work, assume it is collecting more than the result.
Control Tags, Mentions, and Face Recognition
Other people can reveal information about you even when you stay quiet. Enable review-before-posting for tags (Facebook and Instagram both offer "tag review" or "manual approval"), and limit who can tag or mention you. Turn off facial recognition or similar features where the platform offers that choice, so your face is not automatically matched and labeled in photos.
Reduce Ad Tracking
You cannot usually turn ads off completely, but you can limit how much of your off-platform activity is used to target you. On Facebook, clear "Off-Facebook Activity" and adjust Ad Preferences. On TikTok and Instagram, review the ad personalization and data-sharing controls in your account settings. The goal is to make the profile advertisers build about you smaller and less accurate.
Watch for Phishing in Your DMs
Some of the most effective social-media scams arrive as a direct message from a hacked friend's account: a fake login link, a "you were mentioned in this video" trap, or a too-good offer. Treat any link sent by a friend that you did not expect with suspicion, especially if it asks you to sign in. Go to the platform directly in your browser rather than clicking the link.
Download and Review Your Data
Most platforms let you download a copy of the data they hold about you. Reviewing it occasionally is the clearest way to see what you have actually shared and what the platform has inferred. Use the official "Download your data" or "Request your information" tool — never a third-party site that offers to do it for you.
Make It a Routine
You do not need to do all of this at once. A reasonable routine is: set accounts private today, turn on 2FA this week, and do a quarterly audit of apps, tags, and ad settings. Small, repeated habits are what actually lower your daily privacy risk.

Frequently Asked Questions
What is the single most effective social media privacy change?
Switching your account to private (or "protected") and reviewing who can see your posts, tag you, and send you messages. A private account limits your content to people you have approved, which sharply reduces how much of your personal life is exposed to strangers, scammers, and data scrapers.
Should I use my real birthday and phone number on social media?
It is safer not to. Your date of birth and phone number are common pieces of identity used for account recovery and phishing. Use a month and day only if a platform requires a birthday, keep the year private, and consider using an email-based login instead of a phone number where the platform allows it.
How do third-party apps and quizzes get my data?
When you log in to a quiz, game, or helper app "with" a social account, you usually grant it access to your profile and sometimes your friends' data. Remove apps you no longer use in your account's Apps and Websites settings, and only connect tools from developers you trust.
What is the best way to stop targeted ads from using my activity?
Use the platform's Ad Preferences or "Your Ad Choices" controls to limit ad personalization and to clear off-platform (Off-Facebook) activity where available. You cannot usually turn ads off completely, but you can reduce how much outside browsing history is used to target you.
