What's Inside

More than a password manager.

Built for people who take privacy seriously. Every feature designed to keep your data yours.

🔐
Argon2id Encryption
Real Argon2id key derivation (RFC 9106), compiled to WebAssembly. It is memory-hard, which makes GPU and ASIC brute-force attacks far more expensive. AES-256-GCM with a new random IV on every save.
Argon2id: 64 MB memory · 3 iterations · parallelism 1
Library: hash-wasm (WASM, MIT)
Cipher: AES-256-GCM · 96-bit random IV
🎭
Decoy Vault
Set a second password that opens a completely different, fake vault. Protects you under duress — an attacker sees a valid vault with no way to tell it's the decoy. Both passwords produce legitimate decryptions.
Same .vault file · Two separate vaults · Cryptographically indistinguishable
🔑
2FA Code Generator
Store your 2FA secrets encrypted inside the vault. Generate live TOTP codes with a 30-second countdown — compatible with Google Authenticator, Authy, and any RFC 6238 app. Zero network requests, ever.
RFC 6238 compliant · Offline generation · Live countdown timer · Base32 secrets
📝
Secure Notes
Store sensitive text that isn't a password — Windows recovery keys, SSH keys, serial numbers, API tokens, certificates. Fully encrypted inside your vault. Copy with auto-clear clipboard.

All Features

Everything you need,
nothing you don't.

🛡️
Vault Integrity Check
SHA-256 hash stored inside the encrypted payload. Detects if your vault file was tampered with outside the app.
📋
Clipboard Auto-Clear
Copied passwords are automatically wiped after 30 seconds. A visible countdown keeps you informed.
🏥
Password Health Dashboard
Instantly identify weak and reused passwords across your entire vault. Fix them before they become a problem.
🗂
Custom Categories
12 built-in categories plus unlimited custom ones with emoji or symbol icons. Stored encrypted inside your vault.
📁
File Versioning
Every save increments the filename automatically (vault_v2.vault, v3…). Version number stored inside the encrypted vault.
📱
Mobile & PWA ready
Fully responsive mobile layout. Install as a Progressive Web App on Android or iPhone — works offline with a home screen icon, no app store needed.
🏥
Clickable health dashboard
Click weak or reused password counts to instantly see which entries need fixing. One tap to edit and regenerate.
⎘
One-tap copy actions
Copy password, username, URL, or live 2FA code with a single tap. Clipboard auto-clears after 30 seconds.
⬇
Export to CSV or Text
Download your passwords as a CSV (compatible with Google Passwords, Bitwarden, 1Password) or plain text for physical backup. Clear security warning shown before every export.
⌘
Command Palette
Press ⌘K to search entries and trigger any action instantly. Works entirely with keyboard.
How it works

Simple by design.

No setup. No account. No configuration. Just open and use.

1
Open the app
Visit lockmyvault.com/app in any modern browser — or install it as a PWA on your phone or desktop for offline access with a home screen icon.
2
Create your vault
Set a strong master password. Your vault is created instantly — a single encrypted .vault file on your device.
3
Add & manage
Add passwords, store 2FA secrets, write secure notes. Save your vault — it versions automatically.
Security

Built to be audited.

Open source and fully transparent. Anyone can read every line of code.
