SMS Code Filler szerző: lylehust

SMS Code Filler reads the phone-verification codes that arrive in your Mac's Messages app (iPhone SMS forwarding / iMessage) and fills them into the verification-code field on the page automatically — and submits, so you don't have to type or paste anything.

How it works
1. A small background helper (a login LaunchAgent) reads the macOS Messages database with Full Disk Access and caches only recent verification codes locally.
2. The extension detects the verification-code field, picks the code that matches the site, fills it in, and presses Enter / clicks Submit.
3. Auto-fill only uses codes received in the last 30 minutes; used codes are removed from the list. It never fills password, username, or email fields.

Requirements
- macOS (Apple Silicon or Intel) — this add-on does not work on Windows or Linux.
- Firefox 142 or newer.
- An iPhone with Text Message Forwarding enabled to this Mac, so SMS codes reach Messages.app.
- A one-time install of the native helper, plus granting it Full Disk Access. Instructions: https://github.com/lylehust/sms-code-filler

Privacy
Everything happens locally. The extension sends nothing anywhere — no telemetry, no server. It reads codes only from your own Messages database and inserts them into the page you are visiting.
