Flask-Login provides user session management for the python web framework Flask. It handles the common tasks of logging in, logging out, and remembering your users' sessions over extended periods of time.

Flask-Login is not bound to any particular database system or permissions model. The only requirement is that your user objects implement a few methods, and that you provide a callback to the extension capable of loading users from their ID.

It will:

• Store the active user’s ID in the session, and let you log them in and out easily.
• Let you restrict views to logged-in (or logged-out) users.
• Handle the normally-tricky “remember me” functionality.
• Help protect your users’ sessions from being stolen by cookie thieves.
• Possibly integrate with Flask-Principal or other authorization extensions later on.

However, it does not:

• Impose a particular database or other storage method on you. You are entirely in charge of how the user is loaded.
• Restrict you to using usernames and passwords, OpenIDs, or any other method of authenticating.
• Handle permissions beyond “logged in or not.”
• Handle user registration or account recovery.

For detailed information and examples, visit the flask-login documentation.
