Implementing user authentication and authorization
There is a strong foundation of extension modules that can secure API services from unwanted access, such as the Flask-HTTPAuth module. This has the updated utility classes for Basic, Digest, and Bearer token authentication implementation and the Authlib module for building OAuth2 authorization servers based on various grants. These two libraries are updated and reliable, and when combined with other safety procedures, such as password hashing and encryption, can provide baseline protection for Flask applications. Let us start identifying the steps in employing the Flask-HTTPAuth module in our application.
Utilizing the Flask-HTTPAuth module
After you have installed the Flask-HTTPAuth module and its extensions, it can provide its HTTPBasicAuth class to build Basic authentication, the HTTPDigestAuth class to implement Digest authentication, and the HTTPTokenAuth class for the Bearer token authentication scheme.
