This topic will take us further into the authentication process in the Node application. We will be learning how passport, an extremely flexible and modular authentication middleware, is used to authenticate requests for Node.
Any Express-based web application can easily make use of passport without having to bother with integration and implementation issues. Passport implementation is so simple that it does not obstruct the flow of any Express web-based application. Just as we said in the introduction, passport uses modularity to help ensure that its code is clean, maintainable, and easy to integrate with applications. It also possess over 300 sets of strategies that support authentication using the traditional method, involving a username and password and third-party applications such as Instagram, Gmail, GitHub, Facebook, and many others. To use passport for authentication, you must configure the following:
