Troy Hunt's Pwned Passwords API has released version 2, featuring more compromised passwords and improved query security. In response, the developer community has created libraries in seven programming languages to check for pwned passwords: Ruby, Python, Java, PHP, Node.js, C#, and Go. These libraries provide a convenient way to verify password safety and prevent credential stuffing attacks. By using these libraries, developers can help protect users from potential security breaches and promote better password hygiene.
