phpMyID is a small, fairly lightweight,
standalone, single-user Identity Provider for
OpenID authentication. It comprises a single PHP
script that can be used by one individual to run
their own personal OpenID "IdP." The program
requires no external libraries, and has very
minimal requirements. It should run on almost any
server that runs PHP 4 or 5. It requires no
database, and does not access the file system
beyond session handling.
