Password Palace

Self-Sovereign Identity Through Spatial Memory

The Problem

Passwords are broken. People forget them, reuse them, and get phished. Current solutions (password managers, passkeys) still transmit secrets that can be intercepted, and identity remains rented from platforms who can revoke access at will.

The Solution

Password Palace is an **entirely new category** of authentication — not an incremental improvement, but a fundamental rethinking of how humans prove identity. Instead of memorizing arbitrary strings, users leverage natural human memory: **scenes, melodies, screenshots, gestures, and spatial navigation**.

Combined with **zero-knowledge proofs**, your credentials are never transmitted. No one — not even us — can see your secrets.

You remember places, not strings.
You prove knowledge without revealing it.
You own your identity, forever.

Authentication Modalities

Password Palace offers multiple user-friendly ways to prove identity:

Modality	How It Works
3D Scenes	Navigate rooms, interact with objects in memorable spaces
Melodies	Hum or tap a personal tune only you know
Screenshots	Select specific regions of images you remember
Gestures	Draw patterns or air-sign your unique signature
Spatial Paths	Trace routes through personalized environments

**Always evolving**: Password Palace continuously develops new authentication methods, making proof easier and more accessible. The platform grows with users, adding modalities that match how people naturally remember.

Key Differentiators

Secrets transmitted	Never (ZK proofs)	Always
Can be phished	No	Yes
Platform can revoke	No	Yes
Memorable	Yes (natural memory)	No
Crypto-native	Yes (seed phrase storage)	No
