segno VS flask-login

For what it's worth, I opened an issue on github Issue130

I'll just leave this here if anyone wants to make an extension. https://pypi.org/project/segno/

The “Homepage” link on PyPI generally points to the source code repository for the library. For segno the most relevant file is likely encoder.py.

segno: QR-code generator in python that is capable of SVG output

Are this modules good? https://github.com/flask-admin/flask-admin and https://github.com/maxcountryman/flask-login

flask-login: Provides access to the current username

I use Flask-login and implement role based authentication using decorators.

Flask-Login has a closed Issue #19 on GitHub but it actually doesn't answer my question :-/

You can try to look here https://github.com/maxcountryman/flask-login/blob/main/test_login.py

The example code provided by flask-login does it this way, but this only works because it's pulling the User objects from a global hard-coded dictionary, not as in a real-world scenario like a database, where the DB must be checked and User objects created after the user enters their login credentials. And I can't seem to find any other example code that illustrates using a database with flask-login.

What u/MikeDoesDo said. `flask-login` is rather built for the traditional approach to login and user management. It doesn't have a concept of auth tokens or JWT. It uses traditional cookies. The code that actually sets the cookie for the session isn't robust for a production app. Secure tokens have to be signed with robust keys. In addition to strong tokens, you also need measures that prevent brute-force attacks. Third party systems like auth0 bring all of this and more. Besides, with these systems you delegate the login process to the UI and the backend simply needs to verify incoming tokens. The crucial part is that you verify the token contents (audience and such) and the signature. For a production app with sensitive data and money behind it, don't settle for anything less than this.
