Passkeys Backend Authentication

Passwordless TYPO3 backend login via WebAuthn/FIDO2 Passkeys.
One-click authentication with TouchID, FaceID, YubiKey, and Windows Hello.

Overview

nr_passkeys_be replaces traditional password authentication in the TYPO3 backend with modern passkeys. It registers as a TYPO3 authentication service at priority 80, intercepting login requests before the standard password service. When passkey data is present, it performs full WebAuthn assertion verification. Otherwise, it falls through to password login (unless disabled).


Extension key	`nr_passkeys_be`
Package	`netresearch/nr-passkeys-be`
TYPO3	13.4 LTS, 14.x
PHP	8.2, 8.3, 8.4, 8.5
License	GPL-2.0-or-later

Features

Primary authentication -- Passkeys replace passwords, not just augment them
Discoverable login -- Optional username-less login via resident credentials
Admin management -- Admins can list, revoke passkeys and unlock locked accounts
Self-service -- Users register, rename, and remove their own passkeys
Rate limiting -- Per-endpoint and per-account lockout protection
Replay protection -- HMAC-signed challenge tokens with single-use nonces

Supported Authenticators

Platform	Authenticator
macOS / iOS	TouchID, FaceID
Windows	Windows Hello
Cross-platform	YubiKey, other FIDO2 security keys

Installation

composer require netresearch/nr-passkeys-be

Activate the extension in the TYPO3 Extension Manager or via CLI:

vendor/bin/typo3 extension:activate nr_passkeys_be

Configuration

Extension settings are available in Admin Tools > Settings > Extension Configuration > nr_passkeys_be:

Setting	Default	Description
`challengeTtl`	`120`	Challenge token lifetime in seconds
`maxFailedAttempts`	`5`	Failed login attempts before account lockout
`lockoutDuration`	`900`	Lockout duration in seconds (15 min)
`disablePasswordLogin`	`false`	Block password login when passkey is registered
`discoverableLoginEnabled`	`true`	Allow username-less login via resident credentials

How It Works

The extension registers a TYPO3 authentication service at priority 80 (above SaltedPasswordService at 50). When passkey assertion data is present in the login request, it verifies the WebAuthn assertion. When no passkey data is present, it passes through to the next auth service (standard password login) unless password login is disabled.

API Endpoints

Login (public):

POST /passkeys/login/options -- Generate authentication challenge
POST /passkeys/login/verify -- Verify passkey assertion

Self-Service (authenticated, AJAX routes):

POST /ajax/passkeys/manage/registration/options -- Generate registration challenge *
POST /ajax/passkeys/manage/registration/verify -- Complete passkey registration *
GET /ajax/passkeys/manage/list -- List own passkeys
POST /ajax/passkeys/manage/rename -- Rename a passkey label *
POST /ajax/passkeys/manage/remove -- Remove a passkey *

Admin (admin-only, AJAX routes):

GET /ajax/passkeys/admin/list?beUserUid=N -- List any user's passkeys
POST /ajax/passkeys/admin/remove -- Revoke a user's passkey *
POST /ajax/passkeys/admin/unlock -- Unlock a locked-out user *

* Protected by TYPO3 Sudo Mode -- write operations require password re-verification (15 min grant lifetime).
