flask login install

To install Flask-Login, follow these steps:

  1. Open your command prompt or terminal.

  2. Activate your virtual environment, if you are using one. This step is optional but recommended for better project isolation.

  3. Use the following command to install Flask-Login:

pip install Flask-Login

This command will download and install the Flask-Login package from the Python Package Index (PyPI).

  1. Once the installation is complete, you can import Flask-Login in your Flask application by adding the following line of code:

python from flask_login import LoginManager

This allows you to use the functionality provided by Flask-Login in your application.

  1. Finally, initialize the LoginManager object and configure it in your application:

python login_manager = LoginManager(app)

Here, app is your Flask application instance.

The LoginManager object is responsible for managing user authentication and session management. By associating it with your Flask application, you enable Flask-Login to handle user login/logout functionality seamlessly.

That's it! You have successfully installed and configured Flask-Login in your Flask application. You can now use the various features provided by Flask-Login, such as user authentication, session management, and protecting routes that require login.
