Pwned Passwords are 517,238,891 real world passwords previously exposed in data breaches. This exposure makes them unsuitable for ongoing use as they're at much greater risk of being used to take over other accounts. They're searchable online below as well as being downloadable for use in other online system. Read more about how HIBP protects the privacy of searched passwords.

This password wasn't found in any of the Pwned Passwords loaded into Have I Been Pwned. That doesn't necessarily mean it's a good password, merely that it's not indexed on this site. If you're not already using a password manager, go and download 1Password and change all your passwords to be strong and unique.
This password has previously appeared in a data breach and should never be used. If you've ever used it anywhere before, change it!
Password reuse is normal. It's extremely risky, but it's so common because it's easy and people aren't aware of the potential impact. Attacks such as credential stuffing take advantage of reused credentials by automating login attempts against systems using known emails and password pairs.
The Pwned Passwords service was created in August 2017 after NIST released guidance specifically recommending that user-provided passwords be checked against existing data breaches. The rationale for this advice and suggestions for how applications may leverage this data is described in detail in the blog post titled Introducing 306 Million Freely Downloadable Pwned Passwords. In February 2018, version 2 of the service was released with more than half a billion passwords, each now also with a count of how many times they'd been seen exposed. A version 3 release in July 2018 contributed a further 15.6M passwords to bring the total to 517M.
The entire set of passwords is downloadable for free below with each password being represented as either a SHA-1 or an NTLM hash to protect the original value (some passwords contain personally identifiable information) followed by a count of how many times that password had been seen in the source data breaches. The list may be integrated into other systems and used to verify whether a password has previously appeared in a data breach after which a system may warn the user or even block the password outright. For suggestions on integration practices, read the Pwned Passwords launch blog post for more information.
