A Chrome Extension that emulates a Hardware Authentication Device

Download

Install Compare

Chrome Key emulates a Hardware Authentication Device. It is capable of answering Webauthn requests for both registering new keys and authenticating with existing ones.

The purpose is to allow developers to test their applications without requiring having an actual device in hand.

It relies on browser standards such as Web Cryptography API and Concise Binary Object Representation for generation and interaction with key material.

This will never be able to provide the same security guarantees as a real HAD, so use it for development, debugging and testing only.

A 3-post blog series was written, touching different portions of this extension, its guarantees and lack of. The first post of the series may be found here https://blog.joaopeixoto.net/chrome-key-an-extension-story/.

Extension safety

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

CKey requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.
