How can I implement two-factor authentication in my Flask app?

You can use Flask-Security-Too, which provides an easy way to add two-factor authentication. Would you like a code example?

Yes, please provide a code example.

First, install Flask-Security-Too. Then, configure your app with the necessary settings for two-factor authentication. Here's a basic example:

from flask import Flask
from flask_security import Security, SQLAlchemyUserDatastore
from yourapp.models import User, Role

app = Flask(__name__)
app.config['SECURITY_REGISTERABLE'] = True
app.config['SECURITY_SEND_REGISTER_EMAIL'] = False
app.config['SECURITY_TWO_FACTOR'] = True

user_datastore = SQLAlchemyUserDatastore(db, User, Role)
security = Security(app, user_datastore)

What are the prerequisites for using Flask-Security-Too?

You need to have Flask and SQLAlchemy installed, along with a database set up for user management. Would you like help with that?
