MessAuto - macOS SMS and Email Verification Code Auto-Extraction Tool

Overview

MessAuto is an automation tool specifically designed for macOS, capable of automatically extracting SMS and email verification codes (2FA codes) from the system’s built-in Messages (iMessage) and Mail applications, and supports automatic pasting into input fields—greatly simplifying the login verification process.

Core Features

🔍 Automatic Verification Code Extraction

• Smart Monitoring: Simultaneously monitors new messages in macOS’s native Messages and Mail apps.
• Precise Detection: Accurately captures numeric verification codes from messages using configurable keywords (e.g., “验证码”) and regular expressions.

⌨️ Automated Input

• Auto-Paste: Automatically simulates keyboard input to paste the extracted code into the currently focused input field.
• Auto-Enter: Optional feature to press Enter after pasting, enabling one-click login.
• Clipboard-Safe: Uses simulated keyboard input, preserving your clipboard content and enhancing user experience.

⚙️ Highly Customizable

• Configuration File: Supports customizing verification code extraction rules via a TOML-formatted config file, including regex patterns and trigger keywords.
• Flexible Controls: Independently enable or disable SMS/email monitoring, auto-paste, and auto-enter functions.

🪟 User-Friendly Experience

• Floating Notifications: Displays extracted codes in a floating window near the cursor for quick visibility (enabling this automatically forces “clipboard-safe” mode).
• Menu Bar Management: Provides a clean menu bar icon for quick access to settings, logs, and quitting the app.
• Hide Icon Option: Supports temporarily hiding the menu bar icon to keep the interface clutter-free.

Advantages and Features

1. Seamless Integration: Deeply integrates with macOS native apps (Messages, Mail), eliminating the need for third-party services and ensuring privacy and security.
2. Efficiency Boost: Eliminates the tedious steps of manually switching apps, copying, and pasting verification codes—enabling smooth, uninterrupted logins.
3. Privacy & Security: All data processing occurs locally; verification codes are never uploaded to any server. The source code is open-source under the MIT license, ensuring transparency and trust.
4. Resource-Efficient: Built with Rust, offering high performance and low memory consumption.
5. Continuous Updates: Actively maintained by the developer, with future plans to support additional email clients and in-app updates.

Setup Requirements

2. Required Permissions:
   • Full Disk Access: Needed to read Messages/Mail databases. Path: System Settings > Privacy & Security > Full Disk Access.
   • Accessibility Access: Required for simulating keyboard input. Path: System Settings > Privacy & Security > Accessibility.
3. Keep Apps Running in Background: To ensure timely syncing of SMS from iPhone to Mac, keep Messages and Mail apps running in the background for optimal performance.
