The Problem

Every auth system
betrays your users.

Traditional auth collects data it doesn't need. Email, IP addresses, device fingerprints, session metadata. All to answer one question: is this the same person?

✗ Traditional Auth

What they collect

  • ✗ Email address
  • ✗ IP address logged
  • ✗ Device fingerprint
  • ✗ Session metadata
  • ✗ Third-party SDK tracking
  • ✗ Password (hashed, but still)
  • ✗ GDPR liability
✓ YapID

What we collect

  • ✓ SHA-256 hash of public key only
  • ✓ No IP address ever stored
  • ✓ No device data
  • ✓ No metadata
  • ✓ No third-party SDKs
  • ✓ No password exists
  • ✓ Nothing to delete for GDPR
Privacy Score

We didn't just say we're private. We proved it.

Scored across 7 criteria: data collection, IP logging, identity linkability, session encryption, third-party exposure, tracking, and replay protection.

YapID BEST
93%
Ed25519 + AES-256-GCM + zero IP logs + SHA-256 wallet hash. Mathematically unbreakable with 128-bit entropy.
Wallet Connect
67%
Good for crypto users but complex setup, on-chain identity exposure, and RPC call tracking.
Auth0 / Clerk
41%
Email required, IP logged, device fingerprinted, session metadata stored. GDPR compliant but still collects everything.
Sign in with Google
12%
Your real Google identity tied to every login. Tracks across all sites. Shares data with Google.

How it works

12 words. One click.
Permanent identity.

01 — First visit
Create in seconds
Click the button. 12 BIP-39 words are generated locally in your browser. Write them on paper. You're instantly logged in. No form, no email, no waiting.
→ 12 words generated
→ Ed25519 keypair derived
→ Signature sent, not words
02 — Return visits
Auto-login for 1 year
Same browser? One click and you're in automatically. Encrypted session stored in IndexedDB with a non-extractable AES-256 key. Refresh tokens rotate silently.
→ Access token: 1 hour
→ Refresh token: 1 year
→ Auto-renewed silently
03 — New device
12 words = everywhere
Enter your 12 words on any device, any browser, anywhere in the world. Same identity, instantly. Works across every site that uses YapID.
→ Same words = same identity
→ Cross-platform ✓
→ Cross-site ✓
04 — Security
Mathematically secure
2^128 possible combinations. Even all computers on Earth combined cannot brute-force the 12 words. Ed25519 signatures are industry-standard cryptography.
→ 128-bit entropy
→ Ed25519 cryptography
→ Unbreakable by design
05 — Server
Zero knowledge
The server stores only a SHA-256 hash of your public key — not the key itself. No IP, no email, no name. A full database breach reveals absolutely nothing useful.
→ Hash(PublicKey) only
→ No reversible data
→ Breach-proof by design
06 — Control
You own your identity
Logout all devices instantly. Get notified of new logins. Your 12 words are your master key — no company, no server, no government can take your identity away.
→ Logout all devices
→ Login notifications
→ Full user control
