How to Safeguard Your Privacy on the Internet

The internet makes it possible to communicate, shop, work, manage finances, and access services from almost anywhere. These conveniences, however, require people to share personal information with websites, applications, social media platforms, advertisers, and online service providers.

Names, addresses, photographs, browsing histories, account credentials, financial details, and location data may be collected whenever someone uses an online service. If that information is exposed, misused, or stolen, it can lead to identity theft, financial fraud, impersonation, harassment, or reputational harm.

Online privacy is a widespread concern. Pew Research Center found that 81% of U.S. adults were either very or somewhat concerned about how companies use the personal data they collect. The same research found that many people felt they had little understanding or control over what companies did with their information.

Understanding how to safeguard your privacy on the internet can reduce unnecessary exposure and make it harder for criminals, dishonest businesses, or abusive individuals to misuse your personal information.

Limit the Personal Information You Share

The simplest way to protect personal information is to avoid publishing more than necessary. Information shared publicly can be copied, archived, or distributed beyond its original audience.

Avoid publicly posting sensitive details such as:

• Your complete date of birth
• Home address or personal telephone number
• Travel plans and real-time locations
• Identification documents
• Financial account information
• Answers commonly used for security questions
• Photographs showing confidential documents
• Information about children’s schools or routines

Even ordinary details can create risks when combined. A person’s hometown, pet’s name, birthday, and family relationships may help someone guess passwords or answer account-recovery questions.

Review older social media posts regularly. Delete content that reveals unnecessary personal details and restrict who can view photographs, contact information, friend lists, and location history.

Review Privacy Settings on Every Account

Websites and applications may use default settings that make more information public than users realize. Privacy settings should therefore be reviewed when an account is created and periodically afterward.

Check who can view posts, send messages, tag photographs, access location information, or find the account through an email address or telephone number. Disable location tracking when it is not necessary and review which applications have permission to access contacts, cameras, microphones, photographs, and stored files.

Privacy policies can also explain what information a company collects, how it uses that information, and whether data may be shared with advertisers or other organizations. Although these documents can be lengthy, sections addressing data collection, sharing, retention, and deletion are especially important.

Use Strong and Unique Passwords

Using the same password on multiple websites creates a serious security risk. If one company experiences a breach, criminals may try the stolen email address and password on banking, shopping, social media, and email accounts.

Create a different password for every important account. The Federal Trade Commission recommends using long passwords or passphrases and suggests aiming for at least 15 characters. A reputable password manager can generate and store unique credentials, reducing the need to memorize them.

The email account connected to other services requires particular protection because password-reset links are commonly sent there. Someone who controls an email account may be able to take over several other accounts.

Enable Multifactor Authentication

Multifactor authentication requires an additional verification method beyond a password. The second factor may be an authenticator application, security key, fingerprint, facial scan, or temporary code.

The FTC explains that multifactor authentication can prevent someone who has stolen a password from accessing the account without the additional verification factor. Authenticator applications and physical security keys generally provide stronger protection than codes sent through text messages when those options are available.

Enable multifactor authentication first on email, banking, payment, social media, cloud-storage, and tax-related accounts.

Keep Devices and Software Updated

Outdated operating systems, browsers, applications, and security programs may contain vulnerabilities that criminals can exploit. Software updates frequently include patches intended to correct known security weaknesses.

Turn on automatic updates for computers, mobile devices, browsers, applications, and antivirus software. The FTC also recommends securing home Wi-Fi networks, changing default router passwords, and keeping router software current.

Devices should be protected with a passcode, fingerprint, or another screen lock. Encryption and remote device-location or deletion features can offer additional protection if a phone or laptop is lost.

Recognize Phishing and Online Scams

Phishing messages attempt to persuade people to disclose passwords, payment details, identification information, or verification codes. They may appear to come from banks, government agencies, delivery companies, employers, or social media platforms.

Warning signs include unexpected requests for confidential information, urgent threats, suspicious attachments, unusual website addresses, and demands for payment through gift cards or cryptocurrency.

Do not click a link simply because a message appears official. Contact the organization using a verified website or telephone number rather than the information provided in the suspicious message. The Cybersecurity and Infrastructure Security Agency recommends recognizing and reporting phishing attempts rather than responding to them.

Reduce Your Digital Footprint

A digital footprint includes information created through social media accounts, online purchases, public databases, subscriptions, and website activity.

Search your name, email address, and telephone number periodically to see what information is publicly available. Close unused accounts and request the deletion of information that is no longer needed.

People-search websites may collect addresses, telephone numbers, relatives’ names, and other records from publicly available sources. Many provide procedures through which individuals can request that their profiles be removed, although information may reappear and require continued monitoring. The FTC provides guidance about how these services operate and how removal requests can be made.

Know When the Problem May Require Legal Action

Privacy concerns can become legal matters when they involve identity theft, unauthorized disclosure of confidential information, account hacking, stalking, impersonation, doxxing, or the nonconsensual publication of intimate images.

Preserve screenshots, links, usernames, messages, dates, account alerts, and evidence of financial or reputational harm. Do not delete communications that may help establish what occurred.

The legal rights available depend on the type of information involved, how it was obtained, where the affected person lives, and who disclosed it. Someone considering protecting privacy legally may need to evaluate applicable privacy laws, platform procedures, evidence-preservation requirements, and potential remedies before taking formal action.

Immediate threats, stalking, extortion, or suspected criminal conduct should also be reported to the appropriate law-enforcement agency.

Key Takeaways

Safeguarding online privacy requires both careful information-sharing and strong account security. Individuals should limit public disclosures, review privacy settings, use unique passwords, enable multifactor authentication, update their devices, and learn to recognize phishing attempts.

It is also important to reduce unnecessary digital records and monitor the internet for exposed personal information. When privacy violations involve hacking, impersonation, harassment, or unlawful disclosure, preserving evidence and understanding the available legal protections can help prevent further harm.
