Flask, how to store data in session?

Question

Flask

Good evening, the algorithm of actions is as follows, the user enters, the data is added to the session and we can check which links to show him. The user has not logged in - REGISTRATION, LOGIN, if logged in, then a link to EXIT. It would be nice if we could check the data in any template. And is it possible to implement this through flask.session ?

Answer 1

if session.get('authenticated', None) == None:
    # User is NOT authenticated
    # some code here

def authenticate():
    # check user's login and pass
    # ... then
    session['authenticated'] = True
