OoKey Password Manager

Zero-knowledge password manager — autofill, password generation, and secure vault access.

OoKey is a zero-knowledge password manager. It securely stores your passwords on your own device and autofills saved credentials into login forms across the web. ━━ Key Features ━━ 🔒 Zero-knowledge architecture Your master password, encryption keys, and vault contents are never stored on OoKey servers. The server holds only AES-256-GCM ciphertext that cannot be decrypted by OoKey or any third party. 🔑 Strong cryptography Key derivation uses Argon2id with 64 MiB memory cost and 3 iterations. Symmetric encryption uses AES-256-GCM. Authentication uses SRP-6a, a zero-knowledge password proof. The optional recovery key is a 24-word BIP-39 mnemonic. ⚡Autofill OoKey detects login forms automatically and fills your saved credentials in a single click. When you sign in on a new site, an inline prompt offers to save the credentials to your vault. 🛡️Password generator The built-in generator supports customizable length, character classes, passphrases, and usernames. It shows real-time strength feedback and a short history of recently generated values. 📊 Security report A local report flags weak passwords, reused passwords, sites that use plain HTTP, and items missing two-factor authentication. The report runs entirely on your device, with no external API calls. 🌐 Cross-browser Works on Chrome, Edge, Firefox, and Safari. Your vault syncs across browsers and devices through your OoKey account. 📤 Data portability Export your vault to JSON, CSV, or ZIP at any time. Your data remains under your control and is portable to other password managers. 🆘 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 an 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. You can set link expiration and view-count limits. ━━ Privacy and Security ━━ ✅ OoKey does not contact any third-party service. There is no breach database lookup, no analytics, no crash reporter, and no advertising telemetry. The only network destination is the OoKey API. ✅ Servers are hosted in AWS Tokyo (ap-northeast-1). All data remains in Japan. TLS 1.2 or higher is enforced, with HSTS and SameSite=None Secure cookies. Refresh tokens rotate on every use, with reuse detection that revokes the session on suspected theft. ✅ Full technical documentation is available at https://ookey.jp/#docs. ━━ Permissions Justification ━━ ✅storage : Cache encrypted vault data locally for offline use. ✅activeTab : Read and fill form fields on the currently focused tab when the user invokes autofill. ✅scripting : Inject the autofill content script on demand. ✅contextMenus : Provide the right-click autofill menu. ✅alarms : Run the idle auto-lock timer in the background. ✅notifications : Show "Saved to vault" and breach-warning prompts. ━━ About the Developer ━━ OoKey is developed and operated by GOMOAL Inc., Tokyo, Japan.
