[請益] 手機轉帳最安全機制是否簡訊OTP驗證
請教大家....
目前大部分手機銀行app
都可裝置綁定後(現在大都用sim卡電信門號認證綁定設備),
以生物辨識或圖型解鎖,做轉帳動作
近期改版的元大行動app....也把簡訊OTP轉帳改成MOTP推播驗證
為何還有少數幾家堅持轉帳要用簡訊OTP驗證呢?
是這樣的安控機制最安全嗎?

手機非約定轉帳的時候,
1.用戶端手機認證綁定裝置輸入密碼(或生物辨識)
2.銀行端發送簡訊OTP驗證才讓你轉帳
加上第2.步驟是雙保險最嚴格吧。
現在多數銀行已捨棄2.,只要第1.步驟,用戶單方面手機認證就能轉帳,最方便
堅持加上2.多一道銀行把關手續才能轉,除了增加成本(增加麻煩?),也是基於安全考量?
星展的最麻煩,只是登入app看帳號,還要發送OTP驗證。
