What Should You Do If You've Been Breached?
1. Change Your Password
If your email has been in a breach, immediately change your password on that service. Use a strong, unique password that you don't use anywhere else. Use StrongPass to generate a strong password.
2. Check Other Accounts
If you reused that password on other sites, change those passwords too. This is why using a password manager is crucial—you should have unique passwords everywhere.
3. Enable Two-Factor Authentication (2FA)
Enable 2FA on the compromised account and your email. This prevents attackers from accessing your account even if they have your password. Learn about 2FA methods.
4. Monitor Your Accounts
Watch for suspicious activity on the compromised account. Consider checking your credit report if the breach involved financial information.
5. Use a Password Manager
Stop reusing passwords. A password manager like Bitwarden or 1Password generates and stores unique passwords for every site. Compare password managers.
Understanding Data Breaches
What is a data breach? A data breach occurs when hackers gain unauthorized access to a company's database and steal personal information like emails, passwords, credit card numbers, or other sensitive data.
Are breached passwords still dangerous? Yes. If your password was breached, attackers may try to use it on other accounts where you reused it. This is called "credential stuffing." Using unique passwords everywhere prevents this.
How do I prevent being breached? You can't prevent companies from being hacked, but you can protect yourself:
- Use unique passwords on every site (password manager)
- Enable 2FA everywhere possible
- Use strong passwords (16+ characters)
- Check this tool periodically
- Never click suspicious links or download unknown files
Should I be worried? If your email was in a breach years ago and you've since changed your password, you're likely fine. Be concerned if the breach is recent or involves financial information.
