The internet has become an essential part of modern life.

We use it to communicate, work, study, shop, manage money, watch entertainment, store photographs, and stay connected with people around the world. Smartphones and connected devices have made these activities even more convenient.

But there is another side to our increasingly connected lives: online privacy and security.

Every time you create an account, install an app, visit a website, make an online purchase, or share something on social media, you may be providing information about yourself.

Some of that information is necessary for a service to work. Other information may be collected for analytics, advertising, personalization, or other purposes.

At the same time, cybercriminals are constantly looking for ways to steal passwords, financial information, account credentials, and other valuable data.

Understanding online privacy and security can help you make smarter decisions about what you share, which services you use, and how you protect your accounts.

The good news is that you don’t need to be a cybersecurity expert.

A few simple habits can significantly improve your digital safety.

What Is Online Privacy?

Online privacy is about how your personal information is collected, used, shared, and protected when you use digital services.

Personal information can include:

• Your name
• Email address
• Phone number
• Location
• Photographs
• Browsing activity
• Shopping history
• Financial information
• Account information
• Contacts
• Device information

Privacy isn’t necessarily about keeping everything secret.

It’s about having more awareness and control over your personal information.

For example, you might decide that a weather app needs your location while a simple calculator does not.

You might also decide that a social media account should be visible only to friends rather than the public.

These are privacy decisions.

What Is Online Security?

Online security focuses on protecting your accounts, devices, networks, and information from unauthorized access, theft, fraud, malware, and other digital threats.

Common online security measures include:

• Strong passwords
• Multi-factor authentication
• Software updates
• Secure Wi-Fi
• Antivirus and security tools
• Device locks
• Backups
• Phishing awareness

Privacy and security are closely related, but they aren’t exactly the same.

Privacy asks who can access or use your information.

Security asks how that information and your accounts are protected from unauthorized access.

You need both.

Why Online Privacy and Security Matter

Imagine that someone gains access to your email account.

They may find personal conversations, documents, photographs, password-reset links, and information about other accounts.

Now imagine that the same person gets access to your banking account.

The consequences could be even more serious.

This is why online security isn’t just a technical issue.

It can affect your:

• Money
• Identity
• Reputation
• Work
• Relationships
• Personal information

Privacy matters for similar reasons.

Information shared online can sometimes remain accessible for years.

A photograph, comment, or personal detail that seems harmless today may have consequences later.

Use Strong and Unique Passwords

Passwords remain one of the basic defenses protecting online accounts.

A strong password should be:

• Long
• Unique
• Difficult to guess
• Unrelated to obvious personal information

CISA recommends using long, random, and unique passwords and suggests aiming for at least 16 characters. (cisa.gov)

Avoid using the same password for multiple important accounts.

If one password is exposed, criminals may attempt to use it elsewhere.

Consider a Password Manager

Remembering a unique password for every website can be difficult.

A password manager can help.

It can generate and store strong passwords, reducing the temptation to reuse the same password.

The FTC recommends considering a password manager for creating and managing strong passwords. (consumer.ftc.gov)

Protect your password manager with a strong password and MFA where available.

Enable Multi-Factor Authentication

A password shouldn’t always be your only defense.

Multi-factor authentication requires another form of verification when you sign in.

Depending on the service, that might be:

• An authenticator app
• A security key
• A device approval
• A verification code
• Fingerprint recognition
• Facial recognition

The FTC recommends enabling two-factor authentication on important accounts whenever it is available. (consumer.ftc.gov)

Start with your email, financial, work, cloud-storage, and social media accounts.

Protect Your Email Account

Your email account deserves special attention.

Why?

Because email is often connected to your other accounts.

Password-reset links may be sent there.

Important documents may be stored there.

Security notifications may arrive there.

If someone controls your email, they may be able to gain access to other services.

Use a unique password and MFA.

Review your account’s recovery options.

Pay attention to unexpected login alerts.

Learn to Recognize Phishing

Phishing is one of the most common online threats.

A phishing message attempts to convince you to click a link, open an attachment, or provide personal information.

It may appear to come from:

• Your bank
• A delivery company
• Your employer
• A government agency
• A social media platform
• An online retailer
• A friend

The FTC advises consumers to be cautious with unexpected messages that request sensitive information or encourage them to click links or open attachments. (consumer.ftc.gov)

The safest habit is to slow down.

If you receive an unexpected message, don’t immediately click.

Go directly to the organization’s official website or app instead.

Be Careful With Text Messages

Scammers increasingly use text messages because people often trust messages arriving on their phones.

You might receive:

“Your package is delayed.”

“Your account has been locked.”

“Confirm your payment.”

These messages may contain links designed to steal credentials or financial information.

This type of SMS-based phishing is often called smishing.

Treat unexpected texts the same way you treat suspicious emails.

Keep Your Devices Updated

Software updates often include security fixes.

That applies to:

• Smartphones
• Computers
• Tablets
• Browsers
• Apps
• Routers
• Smart devices

The FTC recommends keeping security software, browsers, operating systems, and applications updated and turning on automatic updates when practical. (consumer.ftc.gov)

Don’t assume an update is unnecessary simply because it doesn’t introduce an exciting new feature.

A security patch may be the most important part of the update.

Review App Permissions

Apps may request access to:

• Location
• Camera
• Microphone
• Contacts
• Photos
• Files
• Bluetooth

Some permissions are necessary.

Others may not be.

Review app permissions regularly.

Ask yourself:

Does this app really need access to this information?

If not, consider removing the permission.

Think Before Sharing Personal Information

Before entering personal information into a website, ask why it is needed.

Do you really need to provide your phone number?

Does the service require your date of birth?

Why is a company asking for your location?

Not every request is suspicious.

But understanding why information is being collected can help you make better privacy decisions.

Be Careful What You Post on Social Media

Social media is designed for sharing.

But oversharing can create privacy and security risks.

Think carefully before publicly posting:

• Your home address
• Phone number
• Travel plans
• Workplace details
• Financial information
• Identification documents
• Children’s personal information
• Your daily routine

Information that seems harmless can sometimes help scammers build convincing profiles.

Review Social Media Privacy Settings

Don’t assume your social media account is private by default.

Review:

• Who can see your posts?
• Who can send you messages?
• Who can find you using your email address?
• Who can see your friends or followers?
• Is your location visible?
• Which third-party apps have access?

Privacy settings can change over time.

Check them periodically.

Be Careful With Location Sharing

Location data can reveal a surprising amount about your life.

It may show where you live, work, travel, exercise, or spend time.

Review which applications can access your location.

Where available, consider limiting access to only when the app is being used or using less precise location settings when appropriate.

Understand Cookies and Tracking

Websites use cookies and other technologies for different purposes.

Some help websites function properly.

Others may remember preferences, measure website usage, or support advertising and personalization.

Understanding cookie settings can help you make more informed privacy decisions.

When a website gives you privacy choices, take a moment to review them instead of automatically accepting everything.

Be Careful With Free Services

The phrase “free” doesn’t always mean that a service has no cost.

Some online services may collect information about users as part of their business model.

Before signing up for an unfamiliar service, consider:

• What information does it collect?
• Why does it collect it?
• Who can access it?
• Can you delete your account?
• How long is information retained?
• Can you change privacy settings?

Reading every privacy policy word-for-word isn’t realistic for most people.

But understanding the basics can help you make better choices.

Use Secure Websites

When entering sensitive information online, check that you’re using the legitimate website.

Look carefully at the web address.

Be cautious if the address:

• Looks unusual
• Contains unexpected spelling
• Uses a suspicious domain
• Redirects you through several unfamiliar pages

HTTPS encryption protects information while it travels between your browser and the website, but HTTPS alone doesn’t prove that the website itself is legitimate.

A scam website can also use HTTPS.

Always verify the domain.

Be Careful With Public Wi-Fi

Public Wi-Fi is convenient, but not every network is trustworthy.

Before connecting, confirm the network name with staff when possible.

Avoid performing highly sensitive activities on unfamiliar networks.

For important transactions, using your cellular connection or another trusted network may be a better option.

Secure Your Home Wi-Fi

Your home network connects many devices to the internet.

Secure it by:

• Changing default router credentials.
• Using strong Wi-Fi security.
• Keeping router firmware updated.
• Using a strong Wi-Fi password.
• Reviewing connected devices.

Your router is an important part of your home’s digital security.

Protect Your Smartphone

Your phone may contain:

• Banking information
• Passwords
• Emails
• Photos
• Messages
• Contacts
• Work documents
• Location information

Use a strong screen lock.

Keep the operating system updated.

Install apps from trusted sources.

Review permissions.

Enable device-finding features.

Don’t leave your phone unlocked in public.

Back Up Important Data

Privacy and security aren’t only about preventing unauthorized access.

They are also about being prepared for loss.

A backup can help if your phone or computer is:

• Lost
• Stolen
• Damaged
• Infected
• Accidentally reset

Back up important photographs, documents, contacts, and other files.

Watch for Account Login Alerts

Many services notify you when a new device signs into your account.

Don’t ignore these notifications.

If you see a login you don’t recognize:

1. Change your password.
2. Sign out of unfamiliar devices.
3. Enable MFA.
4. Review account recovery settings.
5. Contact the service if necessary.

Early detection can limit the damage.

Don’t Share Verification Codes

Verification codes help protect accounts.

A scammer may try to convince you to share one.

They might claim to be:

• A bank employee
• A technical-support representative
• A friend
• A company employee

Don’t give the code to someone who unexpectedly contacts you.

If you receive a verification code you didn’t request, check your account for suspicious activity.

Protect Your Financial Information

Be careful when entering financial information online.

Before making a payment, verify:

• The website is legitimate.
• The web address is correct.
• The payment amount is accurate.
• You know who you’re paying.

Don’t allow someone who unexpectedly contacts you to pressure you into transferring money to a “safe” account.

Watch Out for Online Shopping Scams

Before buying from an unfamiliar website, research the seller.

Be suspicious of:

• Unrealistic discounts
• Pressure to buy immediately
• Unusual payment methods
• Missing contact information
• Poor-quality websites
• Fake reviews
• Products that are dramatically cheaper than everywhere else

A professional-looking website doesn’t automatically mean it’s legitimate.

Protect Your Personal Documents

Sensitive documents can contain valuable information.

Examples include:

• Passports
• Driver’s licenses
• Tax documents
• Financial statements
• Employment records

Don’t upload or send these documents unless necessary.

When someone requests a document, verify who they are and why they need it.

Be Careful With AI Tools

Artificial intelligence tools are increasingly integrated into everyday digital services.

People use them for writing, research, coding, planning, image generation, education, and business.

But avoid entering sensitive information into an AI service without understanding how that information may be handled.

Think carefully before uploading:

• Confidential work documents
• Passwords
• Financial records
• Identification documents
• Private conversations
• Sensitive personal information

Convenience should not automatically outweigh privacy.

Delete Accounts You No Longer Use

Over the years, you may create accounts for services you eventually stop using.

Those accounts may still contain personal information.

Periodically review your online accounts.

Delete accounts you no longer need when possible.

For accounts you keep, update passwords and security settings.

Reducing your digital footprint can reduce the amount of information stored across the internet.

Be Careful With Browser Extensions

Browser extensions can provide useful features.

But extensions may request access to websites or browsing information.

Install extensions only from trusted developers.

Review permissions before installing them.

Remove extensions you no longer use.

Teach Children About Online Privacy

Children should learn early that personal information has value.

Teach them not to share information such as:

• Home addresses
• Phone numbers
• Passwords
• School details
• Private photographs
• Family financial information

Explain that not everyone online is who they claim to be.

Encourage children to speak to a trusted adult when something online feels uncomfortable or suspicious.

Help Older Adults Stay Safe Online

Older adults can be targeted by scams involving:

• Government impersonation
• Banking
• Romance
• Investment opportunities
• Technical support

The most important lesson is simple:

Don’t make urgent financial or security decisions without verifying the request.

Encourage family members to ask for help whenever something feels suspicious.

Common Online Privacy Mistakes

Avoid these common mistakes:

• Sharing too much personal information publicly.
• Giving every app unnecessary permissions.
• Using the same password everywhere.
• Ignoring software updates.
• Clicking suspicious links.
• Leaving accounts logged in on shared devices.
• Accepting every privacy setting automatically.
• Downloading unknown applications.
• Sharing verification codes.
• Ignoring suspicious login alerts.

Small mistakes can sometimes create larger problems.

Common Online Security Mistakes

Security problems often happen because people are busy.

You might click a link without checking it.

You might reuse a password because remembering another one seems inconvenient.

You might postpone a software update.

These choices are understandable.

But developing a consistent security routine can reduce risk.
