About this tool
Secure Password Generator & Vault
Overview
Generate random, hard-to-guess passwords using the browser's window.crypto API. Tune the length, uppercase letters, numbers, and special symbols, then store your favorites in a local vault encrypted with the military-grade AES-256-GCM standard. A live strength meter helps you pick a password that actually resists modern attacks.
