One of the biggest online risks isn't sophisticated hacking.
It's reusing a password that was leaked years ago.
Every year, millions of usernames and passwords appear in public data breaches. If you've reused one of those passwords on multiple websites, attackers can automatically try it on other services like email, streaming platforms, or online stores.
Thankfully, checking is easy.
Step 1
Visit a trusted breach notification service such as Have I Been Pwned.
Enter your email address.
If it appears in one or more breaches, don't panic. It simply means one of the websites you used suffered a data breach.
Step 2
Change Passwords
If an old password is still in use anywhere else, replace it immediately.
Every important account should have its own unique password.
Step 3
Use a Password Manager
Remembering dozens of strong passwords isn't realistic.
Password managers generate long, random passwords and store them securely so you only have to remember one master password.
Step 4
Enable Multi-Factor Authentication
Whenever possible, turn on two-factor authentication (2FA).
Even if someone discovers your password, they'll still need your second authentication factor before accessing your account.
Good Password Habits
- Never reuse passwords
- Use long passphrases
- Enable 2FA everywhere you can
- Keep recovery information up to date
- Review important accounts periodically
Final Thoughts
Good security isn't about being paranoid.
It's about making yourself a much harder target than someone who reuses the same password everywhere.
Spending five minutes checking your accounts today could save you hours of frustration later.
