Overview

Zero-click WebAuthn passkey authenticator, password & 2FA TOTP autofill companion for the local WebMCP Vault.

WebMCP Vault Companion is the official Chrome extension paired with the local WebMCP Secure Vault. It provides zero-friction, 1Password-grade credential management, automated WebAuthn passkey authentication, and secure 2FA TOTP autofill directly within Chromium. Key Features: - Instant Passkey Authentication: Dual-mode WebAuthn assertion (ES256 / EC P-256) seamlessly signs in without external dialogs. - Smart Inline Autofill: Detects login and registration fields, matching domains with Alt+K quick-fill. - Local AES-256-GCM Encryption: All credentials reside strictly on your local machine; zero cloud tracking or telemetry. - Seamless 2FA TOTP: Auto-copies and auto-fills 6-digit TOTP codes with live countdown timers. - Developer & Automation Friendly: Works hand-in-hand with WebMCP automation workflows and MCP servers.
