Protect Whatever You Choose 

When you subscribe to the Password RBL API, you choose how you want to use it.  The API is easy to implement and compatible with  anything that can perform hashing and create HTTPS requests.


Secure Password Submission

All passwords submitted to the API are first salted and hashed 

30,000 times and transferred over a secure TLS session. 

Then they're salted and hashed again!


Easy to Understand Docs & Sample Code

Our API Guide is written in plain English and we provide you with sample PHP code  so you can spend more time on your site or app and less time worrying about implementation.


Reporting Only mode for no-impact on End-Users 

You can use the API in Reporting Only mode to determine if your users are picking poor passwords without impacting their choice.
