もう，かれこれ半年近く，webブラウザや，いろいろなアプリケーションでパスワードを使い回せる<\/s>同期できるBitWardenという，アプリとクラウドの総合システムを使ってきました.<\/p>\n\n\n\n

しかし，一番良く使うサイトで使えね〜なぁ状態なので，近々全部uninstallして，クラウドのアカウントも削除する予定です．<\/p>\n\n\n\n

WebブラウザはFirefoxがメインで，iOSとMacではSafariも時々使います．OSの利用割合は，<\/p>\n\n\n\n

macOS>=iOS>Windows>=Linux<\/p>\n\n\n\n

といった感じでしょうか．つい最近FT8をかなりアクティブに運用するようになって（アマチュア無線の話😓），WindowsとLinuxの頻度が逆転したと思います1<\/a><\/sup>2020\/12\/19注: その後いろいろ変わりまして，

\n\n\n\nmacOS>=iOS>Linux>>Windows

\n\n\n\nとなっています．<\/span>．<\/p>\n\n\n\n

さて，セキュリティーの都合上具体的には書けないのですが，とあるサイトでは，プラベートなwikiやその他のwebサービス, 複数の種類のデータベースなどを動かしていて，webブラウザでアクセスします．BitWardenは，同じサイトの別サービスをケースによっては同じアカウントとみなして，サービスを行き来するたびにパスワードを更新しようしてきます．<\/p>\n\n\n\n

Firefoxは賢いことに，同じサイトの同じログイン名のサービスでも，違うサービスとして認識して，パスワードを別々に記憶して提案してくれます2<\/a><\/sup>少なくとも，別のサービスのログイン情報を上書き更新しようとはしません．<\/span>．<\/p>\n\n\n\n

また，BitWardenに期待していた，webブラウザ以外でのパスワードの記憶と提案ってのは，iOSでいくつかあった程度で，全般にはほとんど機能しません．<\/p>\n\n\n\n

ということで，副作用がなければ使わないで残しておいてもいいかと思いましたが，同じサイトの同じログイン名の別のサービスに対してパスワードの更新を勧めてくるのが結構煩わしいので，使うのをやめることにします．<\/p>\n\n\n\n

アプリとプラグインのuninstallだけして，クラウドのアカウントを残すのはセキュリティー的に怖いのでアカウントも削除する予定です．<\/p>\n\n\n\n

今後は，iCloudのKeychainの同期と，Firefoxのパスワード管理+FirefoxSyncの二本立てという，BitWarden導入以前の形態に戻ってやっていくつもりです．<\/p>\n","protected":false},"excerpt":{"rendered":"
