[Flask] Unable to set current_user.authenticated to True

Tue Jul 2 13:01:20 EDT 2019

Hello,

I assume you are using Flask-Login (either directly or via another
extension like Flask-Security). If this is the case, you can import
login_user and call it like login_user(user).

If that does not work, you may want to check if the user is active (ie. not
disabled), as it is the most common culprit when a user canʼt be logged in.

Best,
Gergely
