webauthn 1.0.0

Pythonic WebAuthn

py_webauthn

A Python3 implementation of the WebAuthn API focused on making it easy to leverage the power of WebAuthn.

This library supports all FIDO2-compliant authenticators, including security keys, Touch ID, Face ID, Windows Hello, Android biometrics...and pretty much everything else.

Installation

This module is available on PyPI:

pip install webauthn

Requirements

• Python 3.8 and up

Usage

The library exposes just a few core methods on the root webauthn module:

• generate_registration_options()
• verify_registration_response()
• generate_authentication_options()
• verify_authentication_response()

Two additional helper methods are also exposed:

• options_to_json()
• base64url_to_bytes()

Additional data structures are available on webauthn.helpers.structs. These are useful for constructing inputs to the methods above, and for type hinting. These Pydantic-powered dataclasses provide runtime data validation to help ensure consistency in the shape of data being passed around.

Registration

See examples/registration.py for practical examples of using generate_registration_options() and verify_registration_response().

You can also run these examples with the following:

# See "Development" below for venv setup instructions
venv $> python -m examples.registration

Authentication

See examples/authentication.py for practical examples of using generate_authentication_options() and verify_authentication_response().

You can also run these examples with the following:

# See "Development" below for venv setup instructions
venv $> python -m examples.authentication

Development

Installation

Set up a virtual environment, and then install the project's requirements:

$> python3 -m venv venv
$> source venv/bin/activate
venv $> pip install -r requirements.txt

Testing

Python's unittest module can be used to execute everything in the tests/ directory:

venv $> python -m unittest
