No passwords. No emails to verify. Your device generates the keypair — the private key never leaves your browser. To recover, import the encrypted backup file you download once at registration.

Why this is future-proof
- No password means no leak, no phishing, no reuse risk — ever.
- Ed25519 is the same algorithm SSH, signal apps and crypto wallets use — will be safe for decades.
- Your private key sits in IndexedDB on your device. The server stores only the public key.
- Recovery = re-import the encrypted vault file you downloaded at signup. No email, no SMS, no support ticket.
- User ID is derived from the public key (
zid_…) — no central database controls who you are.
