OTPilot
Auto-fill 2FA codes on any login page
OTPilot started because I was stopping 10 times a day to copy-paste TOTP codes — and I finally got tired of it.
Hey PH! 👋
**How this started**
I work across multiple environments. Every day I was hitting 2FA screens, grabbing my phone, squinting at a 6-digit code about to expire, typing it in — and repeating the whole thing 10 times a day. So I built OTPilot: a Chrome extension that auto-fills TOTP codes on configured pages. That solved my problem.
The first version worked, but setup required pasting in a base32 secret manually. That's fine if you already know what a TOTP secret is. For anyone else, it was a dealbreaker.
**The pivot that changed everything**
When a site shows you a QR code during 2FA setup, that QR encodes an `otpauth://` URI with the service name, account, and secret baked in. That URI also exists somewhere in the page DOM — in a hidden input, a data attribute, or an anchor for people who can't scan QR codes.
v0.0.3 added automatic detection: OTPilot scans the page for that URI, parses it, and shows a floating prompt: "Save [ServiceName] to OTPilot?" One click. The user never sees a base32 string, never opens the extension popup during setup.
That change turned a dev tool into something I'd recommend to my parents.
**Where it is today (v0.0.4)**
- Automatic 2FA setup detection — works on any site that generates an otpauth:// URI
- Zero-click login — detects OTP fields, fills, and submits automatically
- Inline unlock — if the extension is locked, a password prompt appears on the page; enter it, press Enter, it unlocks and fills
- Wildcard URL patterns — useful for *.staging.example.com setups
- MutationObserver fallback — handles SPAs and modals that inject OTP fields dynamically
- Encrypted export/import — AES-GCM + PBKDF2, password-protected
- Everything local — no accounts, no servers, no telemetry
**What's coming**
1. **Firefox support** — next up, using the WebExtensions polyfill so it stays one codebase
2. **Cloud sync** — optional, E2E encrypted; the backend never sees the secrets. One-time payment for personal sync across devices.
3. **Team sharing** — share TOTP codes with teammates without exposing the underlying secret, with instant revocation. Subscription model.
The free local-only tier will always exist.
