Description
Generates a strong, repeatable password for each site from a passphrase using PBKDF2. Nothing sensitive is ever stored. # Chrome Web Store — Submission Text Kit Copy-paste these directly into the Developer Dashboard fields. --- ## Store listing ### Short summary (max 132 characters) **EN:** ``` Generate a strong, unique password for every site from one memorized passphrase. Nothing is stored or transmitted. ``` (116 characters) **JA:** ``` 1つの合言葉から、サイトごとに強力で再現可能なパスワードを生成。合言葉もパスワードも一切保存・送信しません。 ``` ### Detailed description **EN:** ``` Password Forge generates a strong, unique password for each website from a single passphrase that only you remember — nothing sensitive is ever saved. HOW IT WORKS Type your master passphrase, the site's domain, and (optionally) a user ID to tell accounts on the same site apart. Password Forge combines these and runs PBKDF2-HMAC-SHA256 (200,000 iterations) via your browser's built-in Web Crypto API to deterministically derive a password. The same inputs always produce the same password, on any device, with nothing to sync. FEATURES • Choose password length (8–32 characters) • Toggle uppercase / lowercase / digits / symbols independently • "Generation" counter lets you rotate a site's password on demand while keeping the same passphrase • Domain auto-fills from the current tab • English / Japanese interface, switchable anytime • Zero network requests — everything runs locally in your browser WHAT IS STORED Only non-sensitive preferences (default user ID, preferred length, character-type toggles, UI language) are saved locally via chrome.storage.local. Your passphrase and every generated password are NEVER stored or transmitted anywhere. A NOTE ON SECURITY This is a deterministic password generator, not a password manager. Its strength depends entirely on the strength of your passphrase. For your most important accounts, we still recommend a dedicated password manager with multi-factor authentication. ``` **JA:** ``` Password Forgeは、マスターキーとサイトのドメイン、ユーザー名を元に不可逆で一意なパスワードを生成するChrome拡張機能です。 合言葉もパスワードも一切保存されません。 ■ 仕組み 合言葉・対象サイトのドメイン・(同じサイトで複数アカウントを使い分ける場合の)ユーザーIDを入力すると、ブラウザ標準のWeb Crypto APIでPBKDF2-HMAC-SHA256(20万回反復)による鍵導出を行い、パスワードを決定論的に生成します。同じ入力からは、どの端末でも常に同じパスワードが再現され、同期の必要もありません。 ■ 主な機能 ・パスワード長を指定可能(8〜32文字) ・大文字/小文字/数字/記号を個別にON/OFF ・「世代」番号で、合言葉はそのままにサイトのパスワードだけを更新可能 ・現在開いているタブからドメインを自動入力 ・日本語/英語表示をいつでも切替可能 ・通信は一切行わず、すべてブラウザ内で完結 ■ 保存されるデータ 既定のユーザーID・希望のパスワード長・文字種設定・表示言語といった、低機微度な設定のみをchrome.storage.localに保存します。合言葉および生成されたパスワードは一切保存・送信されません。 ■ セキュリティについて これはパスワードマネージャーではなく、決定論的なパスワード生成ツールです。安全性は合言葉自体の強度に依存します。銀行やメインのメールアドレスなど特に重要なアカウントには、専用のパスワードマネージャーと多要素認証の併用をおすすめします。 ``` ### Category Productivity (or: Tools) --- ## Privacy tab (Developer Dashboard) ### Single purpose description ``` This extension's single purpose is to deterministically derive a password for a website from a user-provided passphrase, domain, and optional user ID, using PBKDF2 (SHA-256) — entirely on-device, without storing the passphrase or any generated password. ``` ### Permission justifications **activeTab:** ``` Used only to read the hostname of the currently active tab at the moment the popup is opened, in order to pre-fill the "Domain" field for the user's convenience. No other tab or page data is accessed, stored, or transmitted. ``` **storage:** ``` Used only to save non-sensitive local preferences (default user ID, preferred password length, character-type toggles, UI language) via chrome.storage.local. The passphrase and generated passwords are never stored. No data is transmitted off-device. ``` ### Data collection disclosure checkboxes Leave all data-type checkboxes (Personally identifiable information, Health info, Financial info, Authentication info, Personal communications, Location, Web history, User activity, Website content) **unchecked** — this extension does not collect or transmit any of these; everything happens locally. ### Certifications Check the boxes certifying: - The extension does not sell or transfer user data to third parties for purposes unrelated to the extension's single purpose. - The extension does not use or transfer user data for creditworthiness or lending purposes. ### Privacy policy URL ``` https://<your-github-username>.github.io/<repo-name>/privacy-policy.html ``` (after enabling GitHub Pages on the repository — see README for steps)
