Flask-Cognito-Extended is a Flask implementation of Amazon Cognito. This extension helps quickly implement authentication and authorization solutions based on Amazon's Cognito. It contains helpful functions and properties to handle token based authentication flows.

```bash
pip install Flask-Cognito-Extended
```

```python
from flask import Flask, jsonify
from flask_cognito_extended import (
CognitoManager, login_handler,
callback_handler, get_jwt_identity
)

app = Flask(__name__)

# Setup the flask-cognito-extended extention
app.config['COGNITO_SCOPE'] = "aws.cognito.signin.user.admin+email+openid+profile"
app.config['COGNITO_REGION'] = "us-east-1"
app.config['COGNITO_USER_POOL_ID'] = "us-east-1_xxxxxxx"
app.config['COGNITO_CLIENT_ID'] = "xxxxxxxxxxxxxxxxxxxxxxxxxx"
app.config['COGNITO_CLIENT_SECRET'] = "xxxxxxxxxxxxxxxxxxxxxxxxxx" # optional
app.config['COGNITO_DOMAIN'] = "https://yourdomainhere.com"
app.config['COGNITO_REDIRECT_URI'] = "https://yourdomainhere/callback"

cognito = CognitoManager(app)

# Use @login_handler decorator on your login route
@app.route('/login', methods=['GET'])
@login_handler
def login():

@callback_handler
def callback():
# fetch the unique 'sub' property of the User
