How can I implement authentication in a Flask RESTful API?

You can use Flask-HTTPAuth for basic authentication or Flask-JWT-Extended for token-based authentication.

What are the steps to set up Flask-JWT-Extended?

First, install the package, then configure your app, create a user model, and set up routes for login and token generation.

Can you show me a code example for user login?

Sure! Here's a simple example:

from flask import Flask, request
from flask_jwt_extended import JWTManager, create_access_token

app = Flask(__name__)
app.config['JWT_SECRET_KEY'] = 'your_secret_key'
jwt = JWTManager(app)

@app.route('/login', methods=['POST'])
def login():
    username = request.json.get('username')
    password = request.json.get('password')
    # Verify username and password
    access_token = create_access_token(identity=username)
    return {'access_token': access_token}

What about securing my API endpoints?

You can use the @jwt_required() decorator to protect your routes, ensuring only authenticated users can access them.
