Practicing user authentication and access control with Python

So far, we have explained user authentication and access control in theory. We have also presented several examples on OAuth2.0 and SELinux in the Ubuntu23.04 environment. In this section, we present several practical examples based on Python to further demonstrate the key concepts discussed earlier.

To try the examples, we need to have a practical component. It requires the following Python libraries:

• Requests-oauthlib
• Accesscontrol
• Selinux
• Pycasbin

Using OAuth2.0 in mobile application authentication

To implement OAuth 2.0 in a Python environment for a scenario similar to mobile application authentication, you can use the popular requests-oauthlib library. This library provides a high-level interface to interact with OAuth 1.0/a and OAuth 2.0 providers.

In this section, I will guide you through setting up a basic OAuth 2.0 client that could be used to authenticate a user via a third-party...
