Introduction


Almost every application needs to be able to authenticate users and set permissions. web2py comes with an extensive and customizable role-based access control mechanism. In this chapter, we show you how to customize it by adding fields to the user table, adding CAPTCHA security after repeated failed logins, and how to create Globally Recognized Avatars (Gravatars —icons representing the users). We also discuss the teacher mode of web2py that allows students to share one web2py instance to develop and deploy their applications. Finally, we provide an example of integration with OAuth 2.0 , one of the newest protocols for federated authentication. Web2py also supports ofthe protocols, such as CAS, OpenID, OAuth 1.0, LDAP, PAM, X509, and many more. But, once you learn one, it should be easy to learn the others using the official documentation.
