How do I write an app that logs in through my Apigee credentials?

[#1]

I am writing a web app for our developers. I want them to be able to log in using their existing Apigee credentials. I do not want to create a new user and make them keep track of another set of credentials. I have not been able to find any documentation - how do I do this?
