User reviews

終わったアプリが復活

何年も放置されていて死んだと思っていたアプリがまさかの2025年3月に更新し最新のiOS18まで対応!
このアプリがいいのは二段階認証をQRでエクスポートができるところです。タブレットやパソコン、家族のスマホに…と複数機種に二段階認証を覚えさせるのがQRコードを生成して簡単にエクスポートが出来るのが神です。

デバイス登録できないと思ったら

当方iOS。このアプリの通知をオンにしてアプリを再起動することで、デバイス登録をいざ完了しようとした時の「登録エラー」が解消されて登録できました。
ヘルプを読んだら書いてありました。よく読めと言われればそれまでですが「通知をオンにしよう」にたどり着けるようなエラー文言をその場で出して欲しいです……

最悪

久しぶりに開いたら、『smartkey push通知の設定更新に失敗しました』と出で、何もできない。設定を確認しても問題無し。どうすりゃいいんだよ!ふざけるな。

引き継ぎエラー

何度やってもバグって画面進まず引き継げずに機種変後に使用不可

立ち上がりません

早急に最新OSに対応してください。
