Self-Sovereign Identity

Own your digital identity.

Create a decentralized identity anchored on Polygon, sign in without passwords, and carry verifiable credentials that are yours alone. Your private keys never leave your device.

Features

Every part of SafeIdentity is built so that only you can prove who you are — no central authority, no password to leak.

Your Keys, Your Wallet

An HD wallet (BIP39/BIP44) generated on your device. The seed phrase and private key never touch a server.

Passwordless Login

Sign in to apps with a signature over a one-time challenge. Nothing to phish, nothing to reuse.

Verifiable Credentials

Issue and verify W3C credentials signed by your DID. Anyone can check them, on-chain or off.

Encrypted Vault

A password manager encrypted with a key derived from your PIN (AES-GCM). Your secrets stay on your device.

How it works

Four steps from a fresh device to a login no one can forge.

01

Create

Generate an HD wallet and a did:polygon identifier on your device. Back up your recovery phrase — it never leaves your hands.

02

Sign

When an app asks who you are, it issues a one-time challenge. Your wallet signs it with EIP-191 — no password is ever sent.

03

Verify

The app recovers the signer and checks it against your DID on Polygon. A signature from one key can never be replayed as another.

04

Access

Ownership proven, you're in — the same identity working across every DID-aware app, with no accounts to manage.

Security model

Phishing-proof by math, not policy.

Authentication is a cryptographic signature over a fresh, single-use challenge — there is simply no password to intercept, reuse, or leak.

Keys never leave your device The seed and private key are generated and stored locally, encrypted with your PIN.
ECDSA over secp256k1 The same battle-tested cryptography that secures billions on-chain.
Replay-protected challenges Every login uses a unique, expiring, single-use nonce issued by the server.
No central honeypot There's no password database to breach — verification happens against the public chain.
