Пакет python3-module-flask-login: Информация

Flask-Login provides user session management for 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.
