Introduction
With major data breaches happening almost daily, millions of usernames and passwords end up for sale on the dark web. If you’re reusing weak or old passwords, your accounts may already be exposed without you even knowing. The good news? There are free tools online that let you quickly check if your email, username, or password has been involved in a leak.
In this guide, we’ll cover three trusted websites you can use to see if your personal information has been compromised:
1. Have I Been Pwned (Most Trusted Database)

Have I Been Pwned is one of the most popular and reputable tools for checking if your email address or phone number has been part of a breach.
How to Use It
- Go to the Have I Been Pwned website.
- Enter your email address or phone number.
- Hit the “pwned?” button.
- The site will show you if your data appears in known breaches and list the websites involved.
Why Use It?
- Maintains one of the largest breach databases in the world.
- Regularly updated with new leaks.
- Offers a free notification service if your email appears in a future breach.
2. Databreach.com (User-Friendly Breach Checker)

Databreach is another simple and reliable tool for checking your exposure in recent security leaks.
How to Use It
- Visit Databreach.com.
- Type in your email address.
- Review the results to see if your accounts were compromised in past incidents.
Why Use It?
- Clean, easy-to-use interface.
- Focuses on recent leaks and keeps results straightforward.
- Works as a quick second opinion alongside Have I Been Pwned.
3. ProxyNova Password Leak Tool (Password-Level Check)
Unlike the other two tools, ProxyNova’s Password Leak Tool allows you to search by password itself—not just email. This means you can directly check if a specific password has been leaked.
How to Use It
- Go to ProxyNova’s COMB Leak tool.
- Type in a password you’ve used.
- If it appears in the database, it means hackers already have it.
⚠️ Important Note: Only test old or retired passwords here. Never type your current main password into any third-party website. Instead, use it to confirm whether your older credentials are floating around in public leaks.
Why Use It?
- Shows exact leaked passwords, not just accounts.
- Useful for checking if a password you once used is unsafe to recycle.
- Great for auditing your password hygiene.
What To Do If Your Password Was Leaked
If any of these tools show your credentials have been compromised:
- Change your password immediately on the affected accounts.
- Use a strong, unique password (at least 12 characters, mix of letters, numbers, and symbols).
- Consider a password manager like Bitwarden, 1Password, or LastPass.
- Enable two-factor authentication (2FA) wherever possible.
- Never reuse old passwords, even if you “add a number” to the end.
Conclusion
Your online accounts are only as safe as your passwords. Thanks to tools like Have I Been Pwned, Databreach, and ProxyNova, anyone can quickly find out if their credentials have been exposed in a breach.
