Fast Authenticator

A radically simple, premium, and 100% client-side Time-Based One-Time Password (TOTP) generator. Designed with state-of-the-art glassmorphism aesthetics, Fast Authenticator keeps your two-factor authentication keys completely secure by calculating them directly within your browser. No servers, no tracking, zero databases, and fully functional offline. - 🛡️ 100% Client-Side Web Crypto: Cryptographic signatures are calculated locally using the browser's native Web Crypto API (window.crypto.subtle) for sandboxed, secure execution. - 📱 Adaptive Overlay System: Sleek floating cards on desktop viewports and smooth sliding bottom-drawer sheets on mobile screens running at a locked, GPU-accelerated 60 FPS. - 📂 Flexible Entry Formats: - Camera QR Scanner: Scan visual codes via integrated camera access. - Upload QR Image: Drag and drop or browse standard images (PNG, JPG) containing codes. - Manual Entry: Save accounts with customized issuers, labels, and advanced settings. - List Import (Bulk): Paste raw Base32 secret keys line-by-line to add multiple keys instantly. - ⏳ Upcoming Code Preview: Displays the upcoming code directly underneath the active one, allowing you to copy not only the current OTP but the next token with a single click. - 💾 Local Data Portability: Save accounts directly in your browser's local storage. Easily export and import your saved accounts as standard JSON backup files, or wipe all device data securely with double-confirmation dialogs. - 📲 Installable PWA & Offline Support: Fully compliant Web App Manifest and Service Worker implementation, allowing you to install the application natively on iOS/Android and run it entirely offline. - 🌐 Insecure Context Fallback: Automatic, silent fallback to a custom, pure JavaScript cryptographic engine (SHA-1, SHA-256, SHA-512) and fallback clipboard operations if hosted in HTTP or local development server environments. - Core: HTML5, Vanilla JavaScript, CSS custom variables - Cryptography: Web Crypto API (window.crypto.subtle) - Webcam Scanning: html5-qrcode (lazy-loaded dynamically only when camera or upload features are triggered) - Caching: PWA Service Worker caching static assets and Google Fonts - Aesthetics: Glassmorphic backdrops, harmonious HSL dark/light modes, micro-animations, and Outfit/Plus Jakarta Sans typography. Fast Authenticator is the open-source project yuriionline/fast_auth (https://github.com/yuriionline/fast_auth) by yuriionline, released under MIT.
