NOTICE: This is not a stand-alone application! Perfect Paper Passwords requires a server component to be useful. It is not a "password vault" or "password generator". Please verify that the service you are authenticating with uses PPP on the server side before trying (and rating) this app.
Perfect Paper Passwords is a one-time password system developed by Steve Gibson of the Gibson Research Corporation. It provides a relatively simple, safe, and secure form of multi-factor authentication that virtually anyone can implement. This project's goal is to create a simple, intuitive, Open Source PPP client for Android that mimics the "printed card" paradigm, generating PPP passcodes on the fly as they are needed while maintaining a history of used passcodes for reference.
For more detailed information about the PPP system itself, please see the official PPP site at GRC.com: https://www.grc.com/ppp
