Release Notes

passwordless-lib/fido2-net-lib (Fido2.AspNet)

v4.0.1

Compare Source

Patching Microsoft.Bcl.Memory

v4.0.0: - At last

I believe it's finally time to ship a new stable version, after shipping 17 betas of the 4.0.0 branch.

4.0 contains lots of breaking changes to the API, but also contains support for modern .net features and a lot of cleanups in terms of the webauthn implementation.

We wanted to include some refreshments to our MDS implementation and use of cache -- but we're punting it to a future release.

Here's a migration guide, authored by claude ai to get you started: https://github.com/passwordless-lib/fido2-net-lib/blob/main/Documentation/migration-guide-4.0.0.md

Yeah this version bump requires a few updates to the interfaces. We probably need a ticket to track this work @ike-kottlowski.

Code Review Summary

Reviewed PR: [deps] Auth: Update Fido2.AspNet to v4 (#6328)

Overview

This Renovate-generated PR updates the Fido2.AspNet package from 3.0.1 to 4.0.0. The change is limited to a single line in src/Core/Core.csproj.

Assessment

This PR is incomplete and will not build in its current state.

As noted by @abergs, Fido2.AspNet 4.0.0 contains numerous breaking API changes. The version bump alone, without corresponding code updates, will cause compilation failures.

Breaking Changes Requiring Migration

Based on analysis of the codebase's Fido2 usage (21 files), the following breaking changes from the migration guide will require attention:

1. Status/ErrorMessage properties removed
The result types no longer have Status and ErrorMessage properties. Failures now throw Fido2VerificationException. Affected files:

  • /home/runner/work/server/server/src/Core/Auth/Identity/TokenProviders/WebAuthnTokenProvider.cs (line 122: res.Status == "ok")
  • /home/runner/work/server/server/src/Core/Auth/UserFeatures/WebAuthnLogin/Implementations/AssertWebAuthnLoginCredentialCommand.cs (lines 56-58: assertionVerificationResult.Status != "ok")

2. API method signature changes
Methods like RequestNewCredential, GetAssertionOptions, MakeNewCredentialAsync, and MakeAssertionAsync have updated signatures with wrapped parameter objects.

3. Type changes

  • CredentialMakeResult renamed to MakeNewCredentialResult
  • byte[] to Base64Url type changes for credential IDs
  • AaGuid is now a strongly typed struct

4. Callback delegate changes
IsCredentialIdUniqueToUserAsyncDelegate and IsUserHandleOwnerOfCredentialIdAsync may have updated signatures.

Files Requiring Updates

The following files use Fido2 types and will likely need modification:

  • src/Core/Auth/Identity/TokenProviders/WebAuthnTokenProvider.cs
  • src/Core/Auth/UserFeatures/WebAuthnLogin/Implementations/*Command.cs (4 files)
  • src/Core/Auth/UserFeatures/WebAuthnLogin/I*Command.cs (4 interface files)
  • src/Core/Services/Implementations/UserService.cs
  • src/Core/Auth/Models/TwoFactorProvider.cs
  • src/Api/Auth/Controllers/TwoFactorController.cs
  • Various request/response models

Recommendation

This PR should remain open as a tracking mechanism but requires significant implementation work before merging. The migration should:

  1. Update all Fido2 API call sites to match the new 4.0 signatures
  2. Replace Status == "ok" checks with try-catch for Fido2VerificationException
  3. Update type usages for renamed/changed types
  4. Add or update unit tests to cover the migration changes
  5. Verify WebAuthn registration and authentication flows work end-to-end

The internal ticket (PM-25806) should track this implementation work.
