A lightweight, client-side password generator and manager. No accounts, no servers, no external dependencies — everything runs in the browser and stays on your device.
- Cryptographically Secure: Uses the Web Crypto API (
window.crypto.getRandomValues) to ensure true randomness, far superior to standardMath.random(). - Customizable Complexity: Fine-tune generated passwords with toggleable character sets:
- Uppercase Letters (A-Z)
- Lowercase Letters (a-z)
- Numbers (0-9)
- Symbols (
!@#$%^&*()-_+=[]{}|;:'",.<>/?~) - Spaces
- Ambiguity Reduction: Dedicated option to exclude visually similar characters (e.g.,
o,0,O,|,L,I,l,1,i) to prevent manual entry errors. - Length Control: Generate passwords of any specified length.
- Real-time Entropy Calculation: Instantly calculates the mathematical entropy of the generated password based on the active character sets and length.
- Visual Feedback: A color-coded strength bar provides immediate visual feedback (ranging from "Too Weak" to "Excellent") to ensure passwords meet your security requirements.
- Local Storage Integration: Save your generated passwords securely within your browser's local storage.
- Descriptive Titles: Add descriptive titles to your saved passwords for easy identification.
- Filter & Search: Quickly find specific passwords using the real-time search functionality across your saved items.
- Edit & Rename: Easily update the titles of saved passwords.
- Delete with Safeguards: Remove outdated or unwanted passwords with a confirmation dialog.
- Visibility Toggle: Keep your passwords hidden until you need them, preventing shoulder surfing.
- Export to JSON: Download your entire library of saved passwords (or just your current search results) as a structured JSON file.
- Import from Backup: Easily restore your passwords from a previously exported JSON backup.
- Intelligent Import: Automatically skips duplicate entries to keep your library clean and organized.
- One-Click Copy: Rapidly copy generated or saved passwords directly to your clipboard.
- Interactive Modals: Custom built-in modal system for smooth alerts, confirmations, and renaming prompts without relying on browser-native blocking dialogs.
- Fully Responsive Layout: A clean, responsive interface designed to work flawlessly across devices and screen sizes.
- Instant Status Alerts: Real-time visual feedback for actions like copying, saving, or importing backup files.
- Privacy-First Architecture: All generation and storage happen strictly on the client side. No data is ever sent to or stored on an external server.
- High Performance: A lightweight, zero-dependency implementation resulting in near-instant load times and interaction rates.
