Cloudflare 總算支援 TOTP 了
Cloudflare 宣佈支援 TOTP 形式的 OTP 了：「You can now use Google Authenticator and any TOTP app for Two-Factor Authentication」。 這樣可以重設然後把 Authy 砍掉了，這樣就不用把 OTP 的 secret data 放在別人家了 :o
Facebook 支援 U2F 登入...
Facebook 也支援 U2F (Universal 2nd Factor) 了：「Security Key for safer logins with a touch」。 之前買 Yubico 的 Yubikey 好像不支援 U2F (很久前買的版本)，好像該買幾顆玩具看看了... 剛剛翻了翻 Amazon，好像不少家都有支援 U2F，也許不一定要買 Yubico 的產品 :o
蘋果規劃在 iOS 9 與 OS X El Capitan 引入 2FA 登入機制
蘋果打算在 iOS 9 與 OS X El Capitan 引入 2FA 登入機制：「Apple Adds Two Factor Authentication to OS X and iOS」。 在蘋果的「Two-Factor Authentication in iOS 9 and OS X El Capitan」有詳細說明。 等實際推出的時候再來看看用起來如何...
使用者登入時的錯誤訊息
在「“Invalid Username or Password”: a useless security measure」這篇文章裡談到了使用者登入錯誤時的提示訊息。 通常為了安全考量，「沒有這個帳號」與「密碼錯誤」，我們會給出一樣的錯誤訊息，避免攻擊者可以猜測。像是 Amazon 的畫面： 這樣設計的前提是讓攻擊者不知道這個帳號是不是存在 (如果不存在的話就換其他帳號繼續攻擊)。但這個假設通常是錯的，因為大多數的系統一個 e-mail 綁定一個帳號，所以註冊時就可以分辨： 因此應該提供正確的訊息，而非將資訊隱蔽起來。
Facebook 官方提供 WiFi 登入綁 Facebook 的服務...
記得前陣子在 Twitter 上看到有人想要用 Twitter 認證使用者的消息，結果前幾天就看到 Facebook 提供官方版本：「Get Facebook Wi-Fi for Your Business」。 在「Set Up Facebook Wi-Fi for Your Business」有提到目前有這些產品可以支援： Meraki wireless products Cisco ISR G2 and ASR 1000 Series routers NETGEAR R6300 Smart WiFi router 不過，感覺好像有很多洞可以鑽... Facebook 用了大量的 Akamai 加速，除非在這些頁面特殊處理過 … Continue reading
