## What it is
Flask-JWT-Extended is an open source Flask extension that adds JSON Web Token (JWT) support for protecting routes, with many optional batteries-included features. It supports custom claims, automatic user loading, refresh and fresh tokens, token revocation, and cookie-based storage with CSRF protection.

## Use cases
- add jwt authentication to a flask api
- protect flask routes with  web tokens
- implement refresh tokens in flask
- revoke or blocklist jwt tokens in flask
- store jwt tokens in cookies with csrf protection
- load current user from jwt token in flask
- add custom claims to jwts in flask

## When to choose
- you are building a Flask application or API that needs token-based authentication
- you want batteries-included JWT features like refresh tokens, fresh tokens, and revocation out of the box
- you need cookie-based token storage with built-in CSRF protection
- you want a well-documented, actively maintained, MIT-licensed Flask extension

## When to avoid
- your project does not use Flask (consider a framework-agnostic JWT library like PyJWT instead)
- you need OAuth2/OpenID Connect flows rather than simple JWT auth
- you are building a non-Python backend

## Facets
- artifact type: library
- maturity: stable
- function: auth, middleware, web-framework
- domain: web-development, backend, security, apis
- platform: python
- tags: flask, jwt, -web-tokens, refresh-tokens, csrf-protection, token-revocation
