Flask-Login is a lightweight extension that handles logging users in and out of the site. From the project's documentation, Flask-Login will do the following:
Log users in and out of the site
Restrict views to the logged-in users
Manage cookies and the "remember me" functionality
Help protect user session cookies from being stolen
On the other hand, Flask-Login will not do the following:
Make any decisions about the storage of user accounts
Manage usernames, passwords, OpenIDs, or any other form of credentials
Handle tiered permissions or anything beyond logged in or logged out
Account registration, activation, or password reminders
The takeaway from these lists is that Flask-Login can best be thought of as a session manager. It simply manages user sessions and lets us know which user is making a request, and whether that user is logged in or not.
Let's get started. Use pip to install Flask-Login:
