This repository is a starter template for Flask web applications that need user authentication. Instead of building login, registration, and logout features from scratch each time you start a new project, you can copy this template and have those pieces already wired up and working. It is built with Flask, a popular Python web framework, and uses two Flask extensions for the heavy lifting: Flask-Login handles user sessions, while Flask-SQLAlchemy manages the database side of storing user accounts. The tech stack is straightforward. Flask serves as the core framework. Flask-SQLAlchemy and Flask-Migrate handle database operations and schema changes over time. Flask-Login manages the authentication flow, keeping track of who is logged in across requests. A small library called python-dotenv loads configuration values from an environment file so that sensitive settings like secret keys stay out of the code itself. Getting started involves a few standard steps. You create a Python virtual environment, install the listed dependencies, copy the example environment file, and generate a random secret key using a built-in Python utility. Once that key is saved in the environment file, you run a single command to start the application. The database initializes itself automatically on the first launch, so there is no manual setup script to run. The project is organized into a main application directory plus two feature modules: one for authentication and one for the landing page. Each module keeps its own templates, stylesheets, and logic separated, which makes it easier to find and modify specific parts. By default the homepage requires a logged-in user, and anyone visiting without a session gets redirected to the login page. The template is open source under the MIT license. You can click a "Use this template" button on GitHub to spin up your own copy, then customize it for your project.
