How can I implement user authentication in my Dash app?

You can use Flask-Login along with Dash to manage user sessions and authentication. Would you like a code example?

Yes, please provide a code example for user login.

Here's a simple example:

from dash import Dash, html
from flask import Flask, redirect, url_for, request
from flask_login import LoginManager, UserMixin, login_user, login_required, logout_user

app = Dash(__name__)
server = app.server

login_manager = LoginManager()
login_manager.init_app(server)

class User(UserMixin):
    def __init__(self, id):
        self.id = id

@login_manager.user_loader
def load_user(user_id):
    return User(user_id)

@app.callback(...)
@login_required
def protected_route():
    return 'This is a protected route!'

if __name__ == '__main__':
    app.run_server(debug=True)

This sets up a basic user authentication system.

What about user registration?

For user registration, you can create a form to collect user details and store them in a database. Would you like more details?
