Pillar Box

Pillar Box recreates the "AutoFill for SMS codes" feature that is available in Safari on macOS, but for Chromium based browsers (Chrome, Arc, Edge, etc).

Install both the macOS app and the Chromium extension to get started easily auto-filling SMS codes that you receive via SMS on your iPhone. Please note that SMS sharing between iPhone and your Mac must be enabled.

Key features

• Automatically fill in SMS codes from your messages
• No need to copy and paste codes from messages, or switch between apps
• Secure, nothing leaves your machine

Getting started

The easiest way to get started is to download the latest release from the releases page. Download both files:

• Pillar Box.zip - The native macOS application
• pillar-box-chromium-extension.zip - The Chromium extension

Extract the app from the archive and run it, you may need to go to System Settings > Privacy & Security > Full Disk Access and allow the app for it to run.

Extract the extension from the archive and navigate to chrome://extensions/ in your browser. Enable "Developer mode" in the top right corner, click "Load unpacked" and select the extension you just extracted.

That should be it, go to a website that requires an SMS code and you should see the code automatically filled in.
