kandi X-RAY | webauthn Summary
webauthn allows for log in or second factor authentication for web sites that support the protocol in browsers that also support it, using a physical key (such as a Yubikey 2 security key or Google's Titan USB key), biometrics such as fingerprints and face recognition, and now even your Windows 10 login PIN. Webauthn was announced for Firefox 60 in May 2018 and also later added to Chrome 67 later in 2018. Windows 10 version 1903 distributed in summer 2019 links the Windows password-less login system to webauthn, meaning that the same methods used to log in to Windows 10 can now also be used to log in to (or as second factor authentication for) web sites supporting webauthn. Somewhere along the line Android also added webauthn support for fingerprint readers. Chrome and Firefox on Mac also support webauthn via MacBook built-in fingerprint readers and also USB keys (Yubico 2/5, Titan). Sadly, iOS is lagging behind as of August 2019: nothing on iPhone or iPad supports webauthn, to my knowledge. The idea of the age of password-less logins was widely broadcast in the technical press when Firefox 60 first came out. But the reality is the whole thing is just too complicated for easy adoption. It needs another layer to simplify it for routine use. There are a couple examples in Javascript (see the "coffee" example). But the whole point is that the challenge and authentication must be done server-side. There are also now implementations for Go, Ruby, Python, Java and .NET at webauthn.io, but PHP support is very limited, hence this library. Webauthn is fiendishly complicated, not so much in the cryptography as the way the structures are packed and named. Unnecessarily so (CBOR? What? Surely browsers could have unpacked it from that even if space is at such a premium that keys themselves require this weird binary format; and why not produce the key in PEM format. And so on). So I spent quite a while translating the "coffee" example into a PHP class for Yubico 2 keys, while doing the minimum at the browser side (just unpacking enough to put into a convenient JSON form to transport to the server), and I thought I would share it. Several others have since helped with support for broader application with fingerprints and Windows Hello.

I have implemented some sort of password-less authentication using DUO lab's webauthn using Django. However, I keep getting this error:
ANSWER
Answered 2021-May-20 at 16:36The current version of the webauthn library only supports the following attestation formats:
"fido-u2f""packed""none"
You mentioned you're trying to register an Android device - without seeing a response you're getting back from the call to navigator.credentials.create() I'd make an educated guess that you're getting responses with "android-safetynet" or "android-key" attestation statements which the library is unable to verify.

QUESTION
I tried implementing a fingerprint-based authentication using DUO-lab's Python's webauthn package. I however ran into this error:
ANSWER
Answered 2021-May-10 at 19:46I think the issue is that there's a trailing slash on your ORIGIN value.
Peering into the attestation response's cliendDataJSON, the origin is reported as "https://nacesdecide.herokuapp.com":
Looking at how the Duo WebAuthn library verifies this response, the basic origin comparison is failing because your ORIGIN of "https://nacesdecide.herokuapp.com/" is not equivalent to the response's origin:
QUESTION
When client-side discoverable resident keys are used with WebAuthN, it is not necessary for the relying party to first identify the user trying to sign in. How then does the RP know which user signed in? Does the RP just receive the AuthenticatorAssertionResponse and get the user.id from that?
...ANSWER
Answered 2021-May-06 at 00:47The value of response.userHandle in an assertion response can be used to identify the user that's logging in - it will equal whatever was set to user.id in the PublicKeyCredentialCreationOptions that were passed to navigator.credentials.create().
userHandle is a potentially undefined value, but when resident keys are required during attestation then the authenticator must remember the user ID - see Step 7.4 of the authenticatorMakeCredential operation (the user handle is part of the key the authenticator uses in its internal credentials map to remember a discoverable credential for a given RP ID and user handle).
QUESTION
I am currently developing in a standalone (Not .Net Core Hosted) Blazor WebAssembly app in .Net 5.0. I have been trying to convert a couple Asp.Net MVC WebAuthn examples over into my Blazor app for Passwordless Authentication.
The issue I am experiencing now is due to this app's architecture since it is not a Blazor Server app. The Asp.Net MVC example I am following has everything including the client hosted on the server whereas my app is split Web Client/ Web API architecture.
So far however, I have managed to get most of the way through these differences but now the issue I am having is in the last functionality of registering the credential with the server within the Make Credential request of the Fido2NetLib Library. on line:
...ANSWER
Answered 2021-Apr-21 at 01:45WebAuthn defines the origin to be the fully qualified origin. Per referenced RFC6454, this is the tuple of scheme, host, and port. You can't go breaking the rules without deviating from the standard.
QUESTION
Is there an API or other method for determining if a credential exists on the device that doesn't require taking my fingerprint first in Android?
Currently, I can call getSignPendingIntent(PublicKeyCredentialRequestOptions) with a particular credential id and then I'll be prompted to use my fingerprint. After giving my fingerprint, I'll either get an error response returned if the credential does not exist on the device or get a success response if it does exist.
Is there another method to determine if a credential exists on the device?
One reason for needing to know this is if a customer has registered a credential on device A, but then visits the website on device B. If they are on device B, I don't want to prompt them for a fingerprint to know if they can use their WebAuthN credential. I want to check if the credential exists first and otherwise fall back to the standard authentication method.
...ANSWER
Answered 2021-Apr-21 at 07:00There is no way to be 100% sure. Best possible solution as of today is storing the credential id in local storage (or a cookie) where it was created. That way, you can check if you should offer fingerprint login (aka. Platform Authenticator) option on that device, i.e., in that browser.
There's been some attempts in FIDO Alliance and W3C WebAuthn WG to change this, but so far it has not been done mainly due to privacy reasons.

Install webauthn
PHP requires the Visual C runtime (CRT). The Microsoft Visual C++ Redistributable for Visual Studio 2019 is suitable for all these PHP versions, see visualstudio.microsoft.com. You MUST download the x86 CRT for PHP x86 builds and the x64 CRT for PHP x64 builds. The CRT installer supports the /quiet and /norestart command-line switches, so you can also script it.
