Check for Pwned Passwords
Pwned Passwords are real-world passwords—hundreds of millions of them—that have been exposed in past data breaches. Because these passwords are publicly known, they pose a significant security risk and should not be reused. You can search for them below or download the full list for integration into other systems.

Password Reuse: Convenient—but Critically Dangerous
Using the same password across multiple websites might feel like a simple way to stay organized—but it’s a major security risk. Most people do it. Few understand how dangerous it really is.
When just one site is breached, your email and password can be leaked or sold online. Cybercriminals then use a tactic called credential stuffing—automated attacks that test stolen credentials on thousands of other sites, hoping users reused their login info.
If you’re reusing passwords, one small leak can lead to:
- Unauthorized access to your email, bank accounts, and social profiles
- Identity theft, financial loss, and data compromise
- A total takeover of your digital life
Don’t let convenience open the door to chaos.
Use strong, unique passwords for every account—and secure your site with tools that help prevent automated attacks.
