The summary is as follows: Creating an authentication flow with Strapi involves setting up a Node.js framework that provides an extensible admin panel and built-in features such as authentication, upload, permissions, etc. A boilerplate was created using Create React App to implement the authentication flow using JSON Web Tokens. The authentication views were implemented by creating a Higher Order Component (HOC) that checks if a user can access a specific URL. The routing for the application was set up using React Router DOM, and the form for each auth view was handled using a `forms.json` file. An API call was made to access the app after filling out the form. To implement custom providers like Facebook, the provider's configuration had to be done in Strapi by creating an app on Facebook developers and adding it to the Valid OAuth Redirect URLs field. The SocialLink component was created to handle the social links for each provider.
