Why Smart Key Vault?

In an age of data breaches and privacy concerns, your passwords deserve better protection. Unlike cloud-based password managers that store your credentials on remote servers, Smart Key Vault keeps everything local—on your device, under your control.

• No subscription means no recurring fees
• No tracking means complete privacy

Key Features

Military-Grade Encryption

Your passwords are protected with AES-256-GCM encryption—the same standard used by governments and financial institutions worldwide. Combined with PBKDF2 key derivation using 100,000 iterations, your master password becomes an unbreakable vault key.

100% Local Storage

Every password you save stays on your device. Period. No servers, no sync, no third-party access. Your data exists only where you can physically control it.

Zero Knowledge Architecture

We can't see your passwords because we never have them. Your master password is never stored—only a cryptographic verification hash. Even if someone accessed your encrypted data, it would be mathematically impossible to decrypt without your master password.

Lightweight and Fast

Smart Key Vault is designed to be fast and unobtrusive. Quick popup access lets you find and copy passwords in seconds. Full-page mode gives you room to manage your entire vault comfortably.

One-Click Copy

Copy usernames and passwords instantly with automatic clipboard clearing. Your credentials are automatically removed from the clipboard after a configurable timeout (default 30 seconds) to prevent accidental exposure.

Secure Password Generator

Generate strong, random passwords with one click. Each generated password includes uppercase, lowercase, numbers, and special characters for maximum security.

Import and Export

Easily migrate from other password managers or create secure backups. Import and export your passwords via CSV format with support for up to 10,000 entries.

Auto-Lock Protection

Configurable auto-lock ensures your vault secures itself after a period of inactivity. Choose anywhere from 1 to 60 minutes based on your security needs.

What encryption does Smart Key Vault use?

We use AES-256-GCM encryption with PBKDF2 key derivation (100,000 iterations, SHA-256). This is the same standard used by governments and financial institutions.
