OoKey はあなたのパスワード、カード、ノートを軍用レベルの暗号化で保護します。マスターパスワード一つで、すべてのデバイスから素早くアクセスできます。
About this extension
OoKey is a zero-knowledge password manager that lets you securely store and
autofill all your passwords across the web.

━━ Key Features ━━

🔒 True Zero-Knowledge
Your master password, encryption keys, and vault contents are never stored
on OoKey's servers. The server holds only AES-256-GCM ciphertext that
neither we nor any third party can decrypt.

🔑 Strong Cryptography
• KDF: Argon2id (64 MiB, 3 iterations)
• Symmetric encryption: AES-256-GCM
• Authentication: SRP-6a (zero-knowledge password proof)
• Recovery key: BIP-39 24-word mnemonic

⚡ Fast Autofill
OoKey detects login forms automatically and fills your saved credentials with
one click. When you sign in to a new site, an inline save-prompt offers to
add the credentials to your vault.

🛡 Robust Password Generator
Built-in generator with customizable length, character classes, passphrases,
and usernames. Real-time strength indicator and history of recent values.

📊 Security Report
Analyzes your vault for weak passwords, reused passwords, http:// sites, and
items missing 2FA — entirely on-device, with no external API calls.

🌐 Cross-Browser
Works on Chrome, Edge, Firefox, and Safari. Sync your vault across browsers
and devices via your OoKey account.

📤 Data Portability
Full export to JSON / CSV / ZIP. Your data is always yours — move to another
service whenever you want.

🆘 Emergency Access
Designate trusted contacts who can request access to your vault in an
emergency. Two-layer encryption (RSA-OAEP-2048 + AES-256-GCM) ensures only
the authorized contact can decrypt during the takeover window.

📨 OoKey Send
Share passwords or short notes through expiring, encrypted links. Recipients
do not need an OoKey account. Set link TTL and view-count limits.

━━ Privacy & Security ━━

✅ Zero third-party network calls (no HIBP, no analytics, no Sentry)
✅ Servers in AWS Tokyo (ap-northeast-1) — data stays in Japan
✅ TLS 1.2+ enforced, HSTS, SameSite=None; Secure cookies
✅ Refresh-token rotation with reuse detection
✅ Open architecture — see https://ookey.jp/security for the full whitepaper
