Quick Fix Steps

2. Enter your email address in the search field and click pwned?.
3. Review the results to see which breaches involved your email address.
4. Change the passwords for any affected accounts immediately.

Detailed Instructions

Checking Your Email Address

1. Open your web browser and navigate to https://haveibeenpwned.com.
2. Type your full email address into the search box on the homepage.
3. Click the pwned? button to submit your search.
4. Read the results page carefully. If your email appears in a breach, the site will list the name of the breach, the date it occurred, and what data was exposed (such as passwords, email addresses, or phone numbers).
5. Check specifically whether your password was exposed in any listed breach. If passwords were compromised, treat them as public and change them immediately.

Note: A "breach" means your data was exposed in a security incident at a third-party company. It does not necessarily mean your specific account was hacked, but it does mean your credentials are at risk.

Securing Your Accounts

1. Change your passwords: For every account listed in the breach results, log in and update your password. Use a unique, strong password for each account.
2. Use unique passwords everywhere: If you used the same password for multiple accounts and one was involved in a breach, change the password on all accounts immediately. Attackers often try leaked credentials on other popular services.
3. Use a password manager: Consider using a reputable password manager to generate and store complex passwords.
4. Enable multi-factor authentication: Turn on MFA or two-factor authentication (2FA) on your email, banking, and social media accounts. This adds a second layer of security beyond your password.
5. Check for suspicious activity: Review your account login history and sent items for any unauthorised access.
6. Subscribe to notifications: Consider registering on the breach notification service to be alerted if your email appears in future breaches.

Troubleshooting

No Results Found

If the search returns no results, your email address has not appeared in any breaches indexed by the service. However, this does not guarantee your data has never been exposed, as not all breaches are public or recorded.

Forgotten Passwords

If you cannot log into an affected account to change your password, use the Forgot Password link on the service's login page. If you cannot recover access, contact that service's support team directly.
