Flask-Security allows you to quickly add common security mechanisms to your Flask application.

You can instruct Flask-Security to send a cookie that contains the csrf token. The cookie will be set on a call to GET /login or GET /us-signin - as well as after a successful authentication. This can be very convenient since various JavaScript AJAX packages are pre-configured to extract the contents of a cookie and send it on every mutating request as an HTTP header. axios for example has a default configuration that it will look for a cookie named XSRF-TOKEN and will send the contents of that back in an HTTP header called X-XSRF-Token.

The examples below place secrets in source files. Never do this for your application especially if your source code is placed in a public repo. How you pass in secrets securely will depend on your deployment model - however in most cases (e.g. docker, lambda) using environment variables will be the easiest. ... The following code sample illustrates how to get started as quickly as possible using Flask-SQLAlchemy and the built-in model mixins.

January 9, 2024 - Flask-Limiter is integrated into this example to demonstrate rate limiting, a crucial security measure to protect against abuse, DDoS attacks, and unintended excessive API usage. The Limiter object is created, and a rate limit of "5 requests ...

May 21, 2024 - Unintentionally disclosing the secret key is a common security lapse involving sensitive information, such as the Flask secret key, API key, and passwords, within the source code. Integrating confidential details directly into the source code poses a substantial security risk, as vicious actors can exploit this vulnerability to gain unauthorized access to various services. If you've accidentally hard-coded your secret key and API key in the source code, it will look like this: # Insecure Code api_key = "my_sensitive_api_key" api_url = "https://api.example.com" SEC_KEY = "your_secret_key" # use of secret key app.config["SECRET_KEY"] = SEC_KEY # usage of the API key response = requests.get(api_url, headers={"Authorization": f"Bearer {api_key}"})

Quickly add security features to your Flask application.

May 25, 2026 - Now you can access the login and signup pages that Flask-Security-Too has added to your Flask app for you. For example, going to http://127.0.0.1:5000/login should show you something like this:

June 1, 2025 - A strong security foundation starts with proper application configuration. Never hard-code sensitive secrets (such as SECRET_KEY, API keys, or database passwords) in your source code. Instead, load them from environment variables or use a secrets management tool. This prevents accidental exposure of secrets in version control and makes rotation easier. For example, you can set the Flask secret key via an environment variable:

Flask-Security provides a convenient way to add authentication and authorization to a Flask web app. Flask-Admin provides a convenient way to perform CRUD operations on database tables. This example combines Flask-Security and Flask-Admin so that authorized administrators can maintain the lists of users and roles that control access to the app.

February 6, 2020 - In addition to initializing Flask-Security, SQLAlchemyUserDatastore provides a number of helpful methods representing standard identity management tasks. For example, the create_user method enables us to quickly add new users.

A very simple example of configuring social login with Flask-Security is available in the examples directory.

November 20, 2024 - JWTs are an industry standard for securely transmitting information between parties. In this example, we’ll implement both access and refresh tokens. ... from flask import Flask from flask_jwt_extended import JWTManager from datetime import timedelta app = Flask(__name__) app.config['JWT_SECRET_KEY'] = 'your_jwt_secret_key' app.config['JWT_ACCESS_TOKEN_EXPIRES'] = timedelta(hours=1) jwt = JWTManager(app)

The provided flask_security.uia_phone_mapper() for example performs phone number normalization using the phonenumbers package.

September 20, 2023 - Authentication is a critical aspect of securing any web application. By implementing a strong authentication system, you can ensure that only authorized users have access to sensitive functionality or data. Flask provides various authentication libraries, such as Flask-Login and Flask-JWT, that can simplify the authentication process. Here’s an example of implementing authentication using Flask-Login:

January 14, 2021 - We have to add these lines to protect against cookie attack vectors in our Flask configuration. This will send the cookies over SSL encrypted wire rather than plain text. If an attacker on the same network tries to sniff the network, they will never get the plain text cookies and so these can never be stolen with XSS. We have to use proper HTTP headers to protect our apps. There are some HTTP headers which can be used to implement some sort of security.
