webauthn 1.4.0

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 attrs-powered dataclasses are useful for constructing inputs to the methods above, and for providing type hinting 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
