# Flask user handler blueprint

Flask blueprint that provides all the user handling features that are required by a web application in a database-independent way, including:

• User registration, login and session management.

• Password reset functionality with JWTs.

• Automatic, safe password handling using [Argon2](https://en.wikipedia.org/wiki/Argon2).

The blueprint provides the following routes for a web application: /login, /logout, /register, /request_password_reset and /reset/<token>. All these routes interact with the user database through an instance of the UserHandler class that is a decorator-based database interface, similar to Flask-Login’s LoginManager. All the blueprint routes are backed by ready-to-use HTML templates that are formatted using [BlueprintJS](http://blueprintjs.com/docs/v2/).

## How to use

The blueprint requires the following components to be configured:

• blueprint.user_handler: See the documentation of the UserHandler class for the details.

• LoginManager: This Flask-Login component handles the session management of the Flask application. You need to create an instance of this class and configure it according to the documentation of Flask-Login.

A working demo Flask application showing all the described configuration is included in the library, see demo.py.

## Dependencies

The library requires the following dependencies to be installed.

• Flask-Login: User session management.

• Passlib: Password hashing and verification.

• Argon2_cffi: The preferred Argon2 backend for Passlib. See Passlib’s documentation for more options.
