Google Authenticator 支援備份到 Google Account 的功能
Google 宣布 Google Authenticator (iOS 版、Android 版) 可以備份到 Google Account 上：「Google Authenticator now supports Google Account synchronization」。
We are excited to announce an update to Google Authenticator, across both iOS and Android, which adds the ability to safely backup your one-time codes (also known as one-time passwords or OTPs) to your Google Account.
裡面沒提到傳到雲端上面的時候是不是有加密，翻了一下 Hacker News 上面好像也沒看到：「Google Authenticator now supports Google Account synchronization (googleblog.com)」。
這個算是等很久的功能，我自己避免裝置掛了 (或是遺失) 就把自己被鎖再外面的措施，一個是透過 YubiKey 以外 (如果服務有支援的話)，另外就是在設定時就同時裝到多個裝置上，而且要避免都放在 Google Authenticator 上。
目前應該還是不會用這個，但對於大多數人來說算是方便... 吧？

如果要自己寫 TOTP 的幾個要看的東西...

TOTP 在預設的情況下，其實就是 HMAC-SHA-1 後取後面 32bits，然後轉成數字取 100000 的餘數，而 TOTP 文件是架構在 HOTP 的定義上，把時間切齊 (預設 30secs) 變成整數丟進去攪和，然後特地交代要處理 2038 年超過 Int32…
