Hey Product Hunt! 👋 I built 2FA.AC because I was tired of downloading apps just to generate a single 2FA code — and even more tired of typing my passwords into random websites that might be logging everything. So I built something different: a free, browser-based security toolkit where everything runs locally on your device. Your 2FA secret keys never leave your browser. Your passwords are never sent to our servers. The breach checker uses k-anonymity — only a partial hash is checked, never your actual password. What's inside: 🔐 TOTP 2FA Generator — works like Google Authenticator, right in your browser 🔑 Password Generator & Strength Checker 🔓 Password Breach Checker — k-anonymity protected 🔍 JWT Decoder, Hash Generator, UUID Generator 🌐 DNS Lookup, IP Lookup, WHOIS Lookup, Link Checker 📝 Base64 Encoder, JSON Formatter, QR Code Generator 14 tools total. All free. No account. No tracking. No BS. Would love your feedback — what security tool would you like to see added next? 👇
