我最近写了一篇关于如何为 iCloud 帐户启用 Apple 新的双重身份验证功能^{(authentication feature)} 的文章，这将使您的帐户更加安全。此外，即使您开启了两步验证，两步验证也更加安全。

通常，当您在iPhone 或 iPad^{(iPhone or iPad)}等新设备上登录 iCloud时，您信任的设备上会弹出一条消息，询问您是否要允许登录。如果您授予访问权限，您将获得一个验证码^{(verification code)}，必须在新设备上输入该验证码。

当您自动获取验证码^{(verification code)}时，这一切都很好，但有时您必须自己生成验证码。当我尝试从我的第三代Apple TV登录我的 iTunes Store 帐户^{(Store account)}时，我自己发现了这一点。

它没有给我一个可以单独输入验证码^{(verification code)}的对话框，而是要求我输入密码，然后输入验证码^{(verification code)}。不幸的是，我在任何受信任的设备上都没有看到任何消息弹出。^{(message popup)}

然后我发现我必须从我信任的设备之一手动生成代码。在这篇文章中，我将向您展示如何使用 iOS生成验证码。^{(verification code)}该设备显然必须登录到您尝试在其他地方登录的同一个iCloud 帐户。^{(iCloud account)}

在 iOS 中生成验证码

与几乎所有^{(everything setting)}可以在 iOS 中更改的设置一样，您需要先打开“设置”^(Settings)应用。向下滚动^(Scroll)一点，直到看到iCloud并点击它。

在顶部，您会看到您的姓名以及其他 iCloud 详细信息，例如家庭成员、存储使用情况^{(storage usage)}等。您想要点击您的姓名。

此时，您可能必须输入iCloud 密码^{(iCloud password)}才能继续。在下一个屏幕上，您只有几个选项，例如查看联系信息^{(contact information)}、您的设备和付款方式。我们想点击Password & Security。

最后，我们进入可以实际生成代码的屏幕！就个人而言，我认为该功能应该位于更明显的位置，以便用户更容易找到。

点击获取验证码^{(Get Verification Code)}将立即显示一个六位数的代码，您可以将其输入到您尝试登录的Apple 设备上。^{(Apple device)}

现在，根据 Apple 的网站，您无需在该特定设备上重新输入此验证码^{(verification code)}，除非您注销、擦除设备或更改密码。到目前为止，我在打开双因素一个月后不必再次输入代码。

如果您通过 iCloud.com 从网站登录，则必须选中信任此浏览器^{(Trust this browser)}框，这样您就不必在登录之前继续输入代码。

同样，除非您的Apple^(Apple)设备运行较旧的软件，否则您可能不必使用此功能。最好让您的所有Apple设备保持最新状态，以便它们都能从最新的安全功能中受益。如果您有任何问题，请发表评论。享受！

Generate a Verification Code for Apple Two Factor Authentication

I recently wrote a post on how to enable Apple’s new two-factor authentication feature for an iCloud account, which will make your account much more secure. In addition, even if you had two-step verification turned on, two-factor authentication is even more secure.

Normally, when you sign into iCloud on a new device like your iPhone or iPad, a message will pop up on your trusted devices asking if you want to allow the login. If you grant access, you’ll then get a verification code which has to be entered on the new device.

This all works great when you get the verification code automatically, but sometimes you have to generate the code yourself. I found this out myself when I was trying to log into my iTunes Store account from my third generation Apple TV.

Instead of giving me a dialog where I could enter the verification code separately, it asked me to type in my password, followed by the verification code. Unfortunately, I didn’t see any message popup on any of my trusted devices.

I then found out that I had to generate the code manually from one of my trusted devices. In this post, I’ll show you how to generate a verification code using iOS. The device obviously has to be signed into the same iCloud account that you are trying to log into elsewhere.

Generate Verification Code in iOS

As with just about everything setting that can be changed in iOS, you need to open the Settings app first. Scroll down a little bit until you see iCloud and tap on that.

At the top, you’ll see your name along with other iCloud details like family members, storage usage, etc. You want to tap on your name.

At this point, you may have to enter your iCloud password in order to continue. On the next screen, you only have a couple of options like viewing contact information, your devices and payment methods. We want to tap on Password & Security.

Finally, we get to the screen where we can actually generate the code! Personally, I think the feature should be in a more obvious location so that it’s easier to find for users.

Tapping on Get Verification Code will instantly bring up a six-digit code that you can type onto the Apple device you are trying to log into.

Now according to Apple’s website, you won’t have to reenter this verification code on that particular device unless you sign out, erase the device or change your password. So far, I haven’t had to enter the code again after a month with two-factor turned on.

If you login from the website via iCloud.com, you’ll have to check the Trust this browser box so that you don’t have to keep entering the code before logging in there.

Again, you probably won’t have to use this feature unless you have Apple devices running older software. It’s best to keep all your Apple devices up-to-date so that they are all benefiting from the latest security features. If you have a question, post a comment. Enjoy!
