Online Account Security Checklist

Use this checklist to improve your account security step by step.

Use unique passwords Create a different strong password for every important account.
Turn on 2FA Use two-factor authentication on email, banking, social media, and cloud accounts.
Protect your email Your email can reset many other accounts, so secure it first.
Use a password manager Store strong unique passwords safely instead of reusing weak ones.
Check recovery settings Make sure your recovery email, phone number, and backup codes are safe.
Review account activity Look for unknown devices, suspicious logins, and settings changes.

1. Use Strong Unique Passwords

The first step to protect your online accounts from hackers is using strong unique passwords. If you reuse the same password on many websites, one leak can put several accounts at risk.

Weak password habits

  • Using the same password everywhere.
  • Using short passwords.
  • Using names, birthdays, or personal details.
  • Only adding a number or symbol to an old password.
  • Saving passwords in unsafe notes or messages.

Stronger password habits

  • Use a unique password for every account.
  • Make passwords long and hard to guess.
  • Use a passphrase when you need to remember it.
  • Use a password manager for complex passwords.
  • Change exposed or reused passwords quickly.

2. Turn On Two-Factor Authentication

Two-factor authentication adds a second login step. Even if someone steals your password, they may still be blocked if they cannot complete the second verification step.

Email Protect your email account first because it controls many password resets.
Banking Use 2FA on accounts connected to money, cards, payments, or transfers.
Social media Stop attackers from impersonating you or messaging your contacts.
Password manager If you use a password manager, protect it with 2FA too.

Never share codes

A scammer may ask for your verification code to “secure” your account. Do not share login codes, backup codes, or approval prompts with anyone.

3. Protect Your Email Account First

Your email account is one of your most important accounts. If someone controls your email, they may be able to reset passwords for other accounts.

Email is the master key

Protect your email with a unique password, two-factor authentication, safe recovery options, and regular activity checks.

Check your email account for unknown devices, forwarding rules, filters, recovery changes, connected apps, and sent messages you do not recognize.

4. Use a Password Manager

A password manager can help you create, store, and use strong unique passwords for each account. This makes it easier to avoid password reuse.

Without a password manager

  • You may reuse passwords.
  • You may choose weaker passwords to remember them.
  • You may store passwords in unsafe notes.
  • You may forget which password belongs to each account.

With a password manager

  • You can generate strong passwords.
  • You can store unique passwords safely.
  • You only need to remember one strong master password.
  • You can review weak, reused, or exposed passwords.

5. Check If Your Password Was Leaked

Data breaches can expose old passwords, usernames, emails, phone numbers, and other account details. If your password was leaked and reused, attackers may try it on multiple websites.

Example security warning Your password was found in a known data breach.
Danger The same password may be tried on other accounts.
Danger Scammers may send fake security alerts after a breach.
Do this Change the leaked password and any reused passwords immediately.

Use trusted breach-checking tools and avoid entering your real password into random websites. Read How to Check If Your Password Was Leaked.

6. Review Recovery Settings

Recovery settings help you regain access if you forget a password or get locked out. But if recovery settings are weak or outdated, attackers may abuse them.

Recovery email Make sure it belongs to you and is also secured.
Recovery phone Check that the phone number is still yours and active.
Backup codes Store recovery codes somewhere private and safe.
Trusted devices Remove old or unknown devices from your account settings.

If someone changes your recovery information, they may be able to take the account back later. Review these settings regularly.

7. Review Active Sessions and Devices

Many platforms let you see which devices are signed into your account. Reviewing active sessions helps you spot unauthorized access early.

1

Open account security settings

Look for devices, sessions, login activity, or security activity.

2

Check unfamiliar access

Look for unknown devices, browsers, locations, or login times.

3

Sign out unknown devices

Remove sessions you do not recognize or no longer use.

4

Change the password if needed

If you see suspicious activity, change your password and enable 2FA.

8. Avoid Phishing Links and Fake Login Pages

Many account hacks begin with phishing. A fake email, text message, ad, or website can trick you into entering your password on a fake login page.

Common phishing signs

  • Urgent account warnings.
  • Fake login pages.
  • Strange links or misspelled domains.
  • Requests for passwords or verification codes.
  • Messages claiming your account will be suspended.

Safer habits

  • Do not click unexpected login links.
  • Open the official app or website yourself.
  • Check the URL before entering passwords.
  • Never share 2FA codes.
  • Report suspicious emails when possible.

9. Keep Your Devices Updated

Account security also depends on the devices you use. If your phone, computer, browser, or apps are outdated, attackers may have more ways to steal information or access accounts.

Update your browser Install browser updates to reduce security risks.
Update your phone Keep your mobile operating system and apps current.
Update your computer Install important operating system and security updates.
Remove unknown apps Uninstall apps, programs, and extensions you do not trust.

If you suspect malware or unsafe software, run a security scan with trusted tools and avoid logging into important accounts until the device is clean.

10. Remove Suspicious Connected Apps

Some services allow third-party apps and extensions to access your account. If one of those apps is unsafe, outdated, or unnecessary, it may create risk.

  • Review apps connected to your email account.
  • Remove old apps you no longer use.
  • Remove apps you do not recognize.
  • Review browser extensions and permissions.
  • Be careful with tools that can read messages, contacts, files, or payment information.

Clean up permissions

If an app does not need access anymore, remove it. Fewer connected apps means fewer possible entry points.

11. Watch for Suspicious Activity

Protecting your online accounts from hackers is not a one-time task. You should occasionally check for unusual activity, especially after a breach, phishing attempt, or login alert.

Unknown logins Check for devices, browsers, or locations you do not recognize.
Changed settings Look for recovery changes, profile edits, or new connected apps.
Unknown messages Check sent messages, posts, emails, or DMs you did not create.
Payment activity Review orders, subscriptions, saved cards, and payment history.

If something looks wrong, change the password, sign out unknown devices, enable 2FA, and contact official support if needed.

12. What to Do If You Think an Account Was Hacked

If you notice suspicious activity, act quickly. The faster you respond, the easier it may be to limit damage.

1

Change the password

Use a new strong password from the official website or app.

2

Sign out unknown devices

Remove unfamiliar sessions, browsers, phones, and computers.

3

Enable two-factor authentication

Add a second login step to reduce future risk.

4

Review account damage

Check messages, orders, settings, recovery options, and connected apps.
