How to Make Your Online Accounts More Secure: 12 Simple Steps

Introduction

Your online accounts contain some of your most important personal information. Email accounts, social media profiles, online shopping accounts, cloud storage, banking services, and work platforms may contain private messages, financial information, documents, photos, and other sensitive data.

The good news is that making your online accounts more secure does not have to be complicated. A few simple habits—such as using unique passwords, enabling two-factor authentication, keeping your devices updated, and recognizing phishing attempts—can significantly improve your protection.

In this guide, you’ll learn how to make your online accounts more secure and reduce the risk of unauthorized access, password theft, phishing, and other common online threats.

Why Online Account Security Matters

Cybercriminals often target online accounts because a compromised account can provide access to valuable personal or financial information.

If someone gains access to your email account, for example, they may be able to reset passwords for other services connected to that email address.

A compromised social media account could be used to send scams to your contacts, while a stolen shopping account could expose saved personal or payment information.

Strong account security creates multiple layers of protection, making it harder for an attacker to gain access.

1. Use a Strong and Unique Password for Every Account

One of the most important online security habits is using a different password for every important account.

If you reuse the same password across several websites and one website suffers a data breach, attackers may try that stolen password on your other accounts.

A strong password should be:

• Long and difficult to guess
• Unique to that account
• Free from obvious personal information
• Difficult to predict
• Not reused on other websites

Instead of creating short passwords that are easy to remember, consider using long passphrases or randomly generated passwords.

Avoid These Password Habits

Don’t use passwords such as:

• 123456
• password
• Your name
• Your date of birth
• Your phone number
• Simple keyboard patterns
• The same password for multiple accounts

2. Use a Password Manager

Remembering dozens of unique passwords can be difficult. A password manager can help you create and store strong passwords securely.

A password manager can typically:

• Generate random passwords
• Store login credentials
• Fill passwords into websites and apps
• Help identify reused passwords
• Make it easier to use unique passwords for different accounts

Instead of remembering every password, you generally need to protect the password manager itself with a strong master credential and, where available, additional authentication.

3. Turn On Two-Factor Authentication

Two-factor authentication (2FA) adds another security layer to your account.

Without 2FA, an attacker who obtains your password may be able to sign in. With 2FA enabled, the attacker may also need a second authentication factor.

Depending on the service, the second factor may be:

• An authenticator app
• A security key
• A passkey
• A text message code
• Another approved authentication method

Whenever a service offers stronger authentication options, review them and choose an option appropriate for your situation.

4. Consider Using Passkeys

Passkeys are a newer authentication method designed to reduce reliance on traditional passwords.

Instead of typing a password, you may authenticate using a device-based method such as a fingerprint, face recognition, or device PIN.

Passkeys can help protect against certain types of phishing because they are designed to work with the legitimate website or service for which they were created.

If your important accounts support passkeys, consider adding one as part of your security strategy.

5. Protect Your Email Account First

Your primary email account deserves special attention.

Many online services use email for password resets and account recovery. If someone gains control of your email, they may potentially use it to access other accounts.

For your primary email account:

• Use a unique password or passkey.
• Enable strong multi-factor authentication.
• Review recovery information.
• Check recent login activity.
• Remove unfamiliar devices.
• Keep your recovery options up to date.

Securing your email can therefore help protect many other accounts connected to it.

6. Watch Out for Phishing

Phishing is one of the most common ways attackers try to steal login information.

A phishing message may pretend to come from a bank, social network, online store, employer, delivery company, or another trusted organization.

It may ask you to:

• Verify your account
• Reset your password
• Confirm payment information
• Click an urgent link
• Download an attachment
• Provide a security code

Be cautious when a message creates urgency or asks you to provide sensitive information.

Before Clicking a Link

Ask yourself:

1. Was I expecting this message?
2. Does the sender appear legitimate?
3. Is the website address correct?
4. Is the message pressuring me to act immediately?
5. Can I open the official website directly instead?

When in doubt, avoid clicking the message’s link and visit the service through its official app or website instead.

7. Keep Your Devices and Apps Updated

Security updates can fix vulnerabilities in operating systems, browsers, applications, and other software.

Turn on automatic updates where practical and regularly update:

• Windows, macOS, Linux, or other operating systems
• Android or iOS
• Web browsers
• Mobile applications
• Security software
• Important desktop applications

An outdated device may contain known security weaknesses that attackers can exploit.

8. Review Your Active Sessions and Devices

Many online services allow you to see where your account is currently signed in.

Check these settings periodically.

Look for:

• Unknown devices
• Unfamiliar locations
• Old phones or computers
• Sessions you no longer use
• Unexpected login activity

If you see something you don’t recognize, sign out of the suspicious session, change your password if appropriate, and review your security settings.

9. Remove Old and Unused Accounts

Old online accounts can become security risks if you no longer monitor them.

If you have accounts you haven’t used for years, consider whether you still need them.

For accounts you no longer need:

1. Sign in.
2. Remove unnecessary personal information where possible.
3. Download anything you need.
4. Disconnect linked services if necessary.
5. Close or delete the account according to the provider’s process.

Reducing the number of accounts you maintain can make your digital life easier to manage.

10. Be Careful on Public or Shared Devices

Avoid entering sensitive login information on computers that you do not control.

For example, a public or shared computer may contain malicious software or may not be properly secured.

If you must use a shared device:

• Avoid saving passwords.
• Do not select “Remember me.”
• Sign out completely.
• Avoid accessing highly sensitive accounts when possible.
• Never leave your account open after you finish.

Your own updated device is generally preferable for sensitive account activity.

11. Review Third-Party App Access

You may have connected different apps and websites to your Google, Microsoft, Apple, social media, or other accounts.

Over time, some of these connections may no longer be necessary.

Review your account’s connected applications and remove access that you no longer need.

This reduces the number of third-party services that can interact with your account.

12. Secure Your Account Recovery Options

Account recovery settings are extremely important.

Check that your recovery email address and phone number are current and belong to you.

Also review:

• Recovery email
• Recovery phone number
• Backup codes
• Trusted devices
• Authentication methods
• Security questions, where applicable

Store backup codes securely rather than leaving them in an easily accessible location.

How to Check If Your Account Has Been Compromised

There are several warning signs that an account may have been compromised.

Watch for:

• Password reset emails you didn’t request
• Login alerts from unfamiliar devices
• Messages sent from your account without your permission
• Changes to account settings
• Unknown purchases
• New recovery information
• Unfamiliar connected applications

If you suspect unauthorized access, act quickly.

Change the password from a trusted device, sign out of other sessions where possible, enable stronger authentication, review account activity, and follow the service provider’s account-recovery process.

What to Do If Your Password Has Been Exposed

If you learn that a password has been exposed in a breach, don’t continue using it.

Take these steps:

1. Change the password immediately.
2. If you reused that password elsewhere, change those accounts too.
3. Enable multi-factor authentication.
4. Review recent account activity.
5. Check connected applications.
6. Look for unauthorized changes.
7. Be especially careful of phishing messages after a breach.

A password that has been exposed should be considered unsafe even if you have never noticed suspicious activity.
