Web サイトで同じパスワードを使いまわすことが挙げられる．パスワードリスト攻撃を防ぐためには推測が困難なパスワード使用することやパスワードを Web サイトごとで使い分けることが求められているが，ユーザが記憶できるパスワードには限界がある．そのため，パスワードマネージャを用いることがパスワードリスト攻撃の対策の 1 つとして挙げられる．パスワードマネージャはユーザのパスワードと ID の組を記憶 ・管理できるアプリケーションであり，ユーザは自身が設定したマスターキーを用いた認証を行う事でパスワードや ID を取り出すことができる．なお，マスターキーとして扱う情報はパスワードに限らずユーザの生体情報も利用できるアプリケーションも存在している．ただ，安全な多要素認証をサポートしており，パスワードマネージャの使用環境に応じてポリシーを柔軟に変更できるパスワードマネージャは知られていない．そこで本稿では，線形秘密分散法を用いて多要素認証を柔軟に変更できるパスワードマネージャを提案し，実装
