Your Keys. Your Identity.
Unstoppable.
24 words. That's all you need. No email, no account, no server dependency. Even if we disappear, your passwords survive.
Three Pillars of Digital Identity
One vault. Complete control. Zero compromise.
Zero-Knowledge Passwords
AES-256-GCM encryption. SRP-6a mutual authentication. Your master password never leaves your device.
Authorization Lifecycle
OAuth tokens, API keys, service accounts -- centralized management with auto-refresh and instant revocation.
AI Agent Gateway
MCP protocol lets AI assistants securely access credentials under policy-controlled, fully audited access.
How It Works
Generate Seed
24 words generated on your device. No email needed.
Derive Keys
All encryption keys derived from your seed phrase.
Use Anywhere
Browser, extension, or AI agent via MCP protocol.
Recover Anytime
24 words = full recovery. Even without us.
The Unstoppable Promise
What makes Auth Box different from every other password manager.
No Email Required
Create a vault in 45 seconds. No signup, no account, no email.
Survive Without Us
If Auth Box disappears tomorrow, your vault still works. Your seed phrase is the only key.
Passwords Without Storage
Derive passwords deterministically from your seed + site name. Vault can be empty.
Import Everything
Migrate from 13 password managers: Apple, Google, Chrome, Firefox, 1Password, Bitwarden, and more.
Encryption Architecture
Your master password derives three independent keys. The server never sees any of them.
