Digital Privacy Basics: Simple Steps to Protect Your Personal Information Online

Every time you browse, shop, post or use an app, information about you is collected. Some of it is needed to make services work, and some is gathered for advertising or other purposes. You cannot eliminate data collection entirely, but a few basic habits can significantly reduce your exposure and make it harder for criminals to misuse your information.

Start With Strong Account Security

• Use a unique, long password for each important account, preferably with a password manager.
• Turn on two-factor authentication wherever it is offered, especially for email, banking and social media.
• Review the devices and sessions that are signed in to your main accounts, and remove ones you do not recognize.

Review Privacy Settings

Social media, search engines, phones and streaming services all have privacy controls. Look at who can see your posts, whether your location is shared, how your activity is used for ads and whether contacts are uploaded. Check these settings now and again because updates sometimes change defaults.

Be Careful With App Permissions

Many apps ask for access to your location, contacts, camera, microphone or photos. Grant only what is needed for the app to function, and choose the option to allow access only while using the app when available. Delete apps you no longer use, and review permissions in your phone's settings.

Limit What You Share Publicly

Be mindful about posting details such as your full birth date, home address, travel plans or photographs that reveal your location. Information that seems harmless can be combined by scammers to impersonate you or answer account recovery questions.

Learn to Spot Phishing

• Be suspicious of unexpected messages that create urgency or ask for passwords, codes or payments.
• Check the sender's actual address and hover over links to see where they lead.
• Go directly to a company's official website or app instead of using links in a message.
• Never share verification codes with anyone who contacts you.

Use Your Browser Wisely

Choose a browser with solid privacy and security features, keep it updated and consider blocking third-party cookies and trackers. Extensions can help, but install only a few from trusted sources, because some can read everything you do online. Use private browsing for sensitive searches, understanding that it does not make you anonymous.

Protect Your Devices

• Install updates for your operating system and apps promptly.
• Use a screen lock with a PIN, password or biometric.
• Enable device encryption and remote find-and-wipe features.
• Back up important files to a secure location.

Be Selective With Email and Sign-Ups

Use a separate email address or an alias service for newsletters and shopping to reduce spam and keep your main address private. Read what a service collects before you agree, and consider whether a free product is worth the data it takes in return.

Clean Up Periodically

Delete accounts you no longer need and unsubscribe from lists. Check whether your email addresses appear in known data breaches using reputable breach notification services, and change passwords if they do.

Privacy is a matter of degrees. Small steps, taken consistently, make a real difference.
