2FA Master — Premium Authenticator

Premium 2FA authenticator with secure TOTP code generation

2FA Master — Beyond Security, A Statement of Taste Say goodbye to ugly authenticators. Welcome to dark-gold美学 (aesthetics) for two-factor authentication. Most 2FA tools either look stuck in 2015 or force you to sync your secrets to the cloud — and hold your breath. 2FA Master gives you premium design and data sovereignty at the same time. Your keys stay yours. Always local. Never uploaded. ✨ Key Features 🔐 TOTP Standard Compliant Built on RFC 6238. Supports SHA-1 / SHA-256 / SHA-512, 6 or 8-digit codes, 30 or 60-second periods. Works with Google Authenticator, Microsoft Authenticator, Authy, and all mainstream formats. 📸 Screenshot to Add — One Second Setup See a QR code? No need to grab your phone. Just draw a box around it on any webpage — the otpauth:// link is automatically recognized and added. Supports all standard TOTP QR codes. 🎨 Dark-Gold Aesthetics — For Detail Freaks Deep dark theme × warm gold accents. Not another gray toolbox. Circular countdown timers, brand-colored icons (auto-matched for 55+ services), smooth animations — every pixel is polished. 🔒 AES-256-GCM Local Encryption Optional master password protection. PBKDF2 key derivation + Web Crypto API hardware-grade encryption. All data stored only in your browser — no upload, no sync, no traces. Your keys, your rules. 🌍 Bilingual + Light/Dark Themes Auto-switches with your browser language, or choose manually. Dark mode for your eyes, light mode for clarity — each theme is independently tuned, not just inverted colors. 📋 Drag to Sort, Batch Management Rearrange account cards like on your phone home screen. Search, filter, one-click copy, QR migration — managing 50 accounts is as easy as managing 5. 🔄 QR Migration, Seamless Device Transfer Every account can generate a standard migration QR code. Scan with any other authenticator app to move accounts — no more transfer headaches. ⚡ Millisecond Real-Time Refresh Circular progress bar updates every second. Breathing flash reminder 5 seconds before code expires. One click on any card copies the code to your clipboard — paste and go. 🛡️ Import/Export, Backup Without Worry Supports plain JSON export and AES-encrypted export. Encrypted backups can be safely stored in the cloud or transferred. Plain export for bulk migration. 🎯 Who Is This For? Developers / IT Ops — Manage dozens of 2FA accounts for GitHub, AWS, Cloudflare, etc. Privacy-First Users — Reject cloud sync, keep full local control. Aesthetic Connoisseurs — If you care about how your tools look, you've found your match.
