    Faktor – The missing 2FA code autocomplete for Chrome▲26

    Hi everyone, Kenneth here. As a loyal Chrome user, I was frustrated that one of Apple's most loved features from Safari and iOS wasn't available in Chrome. So, I built Faktor—a tool that grabs 2FA security codes from your iPhone and autofills them in Google Chrome on your Mac. Faktor is a native macOS app with a small Chrome extension, and once you install Faktor its easy to forget that this functionality isn't native to Chrome. Enjoy!
