只會要求您提供使用者名稱及密碼 為保障這些應用程式安全無虞

you’ll need to use a special password, called an application-specific password, instead

您必須使用稱為應用程式專用密碼的特殊密碼

of your regular account password. Application-specific passwords are generated by Google upon your

而不是日常使用的帳戶密碼 您必須提出要求，Google 才會產生應用程式專用密碼

request, and you do not need to remember them since you should only need to enter them once!

由於您只需要輸入這組密碼一次 所以也不必費心記憶！

To illustrate, let's set up the Mail app on an iPhone using an application-specific password.

為讓您更加瞭解，現在讓我們利用應用程式專用密碼 在 iPhone 上設定郵件應用程式

First you need to create an application-specific password. Go to your Account Settings page

首先，您必須建立一組應用程式專用密碼 請前往您的 [帳戶設定] 頁面

and click "Authorizing applications & sites." Enter the name of the application this password

然後按一下 [授權應用程式和網站] 接著請輸入專用密碼所屬的應用程式名稱

is for -- in this case, "Gmail on my iPhone." Then, click generate.

此範例使用的名稱是 Gmail on my iPhone 然後按一下 [產生]

Enter the application-specific password on your iPhone … And you’re done!

在 iPhone 上輸入這組應用程式專用密碼 然後就大功告成了！

We know application-specific passwords are long and hard to remember -- that's why you

我們瞭解應用程式專用密碼又長又難記 所以您根本

don't have to! You should only need to enter these passwords once per application or device,

不需要強記！在每個應用程式或裝置中只要 輸入這些專用密碼一次

and you can always revoke and generate a new password if needed.

必要時可以隨時撤銷並產生 一組新的密碼
