The latest Apple ID security system is two-factor authentication.
Your security has been updated without your knowledge and you want to unlock it.
In this article, we’ll provide an overview of two-factor authentication, how to unlock it, and what to do if you haven’t received a verification code.
What is the function of two-factor authentication?
Without further ado, let me start by explaining what type of two-factor authentication the system is.
What is two-factor authentication? Apple ID security
Two-factor authentication is a system introduced as a mechanism to protect the security of the Apple ID.
Most modern web services use 2-step verification to log into sites with passwords, one-time passwords sent to SNS, etc. Apple also uses two-step verification in the same way. Two-factor authentication is its name.
Two-factor authentication with verification codes sent to trusted phone numbers and devices
In the case of other web services, you can log in to the site by entering a phone number when registering as a member, receiving a code that can only be used temporarily for that phone number, and entering that number, but it’s only two-factor authentication There are features.
As you know, Apple develops and sells hardware such as iPhone and Mac, but it is originally developed software.
With a device loaded with software installed only in Apple products, the confirmation code is delivered not only to the registered phone number but also to a trusted device signed in with the same Apple ID.
So, even if your Apple ID and password are leaked, you can avoid accessing your personal information because the login notification will also be sent to your trusted device.
Currently (March 2023), you cannot create an Apple ID other than two-factor authentication
As of March 2023, it is no longer possible to create an Apple ID securely other than with two-factor authentication.
This is just a guess, but it is expected that the previous security will not be a countermeasure against phishing scams, which have been increasing in recent years.
Two-factor authentication cannot be turned off
As of March 2023, two-factor authentication can no longer be revoked.
Even if you create a new Apple ID or update your Apple ID to two-factor authentication, you can’t cancel it, so be careful when making changes.
In particular, if you do not want to change it, you will be prompted to update to two-factor authentication immediately after updating iOS.
Only if you accidentally switch to two-factor authentication can you cancel within two weeks
However, if you updated your Apple ID after iOS update, you can unlock the previous security within two weeks.
So, as of March 2023, two-factor authentication can only be revoked if you unintentionally update after an iOS update.
Please also note that the cancellation period is set at two weeks, so if it exceeds two weeks, you will not be able to cancel it.
Can update via security question (previously security)
Previously, AppleID security was secret questions or two-step verification.
Since two-step verification is not commonly used, many old Apple users have used secret questions.
Users who are still using Secret Questions can still update after an iOS update, but they can also update from Settings.
If you have multiple Apple devices, you will receive a verification code on all of them
With two-factor authentication, if you have multiple Apple devices and are signed in with the same Apple ID, you can receive verification codes on all of them.
In my case, I’m using an iPhone, iPad, Mac, and Apple Watch, and when I need a verification code, I can receive it on any device.
Many people think that there is no problem with secret questions, but if you use multiple Apple devices, you can’t unlock them, but two-factor authentication is more secure, so please consider updating. give me please.
Advantages/disadvantages of removing two-factor authentication
So far, we have provided an overview of two-factor authentication.
I think you are aware that you cannot unlock an Apple ID made with two-factor authentication or if it has been more than two weeks since you updated it.
What are the pros and cons of disabling two-factor authentication? Here are the pros and cons of unlocking your Apple ID.
The advantage of two-factor deauthorization is that you can save yourself the hassle of obtaining and entering a verification code when you sign in to your Apple ID.
Also, when you change the iPhone model and transfer data, you may see beeps on SNS etc. Confirmation code cannot be received and data cannot be transferred.
In order to avoid the risk of such problems, it is easiest not to use two-factor authentication.
The downside of disabling two-factor authentication is that it reduces security.
Secret questions may be known to people close to you.
I don’t want to suspect someone close to me, but since we live in an era where we have a lot of important data on our smartphones, there is a risk of data being accessed.
In order to reduce these risks, Apple officially recommends using two-factor authentication without canceling it.
How to cancel two-factor authentication
Here’s how to turn off two-factor authentication.
- Apple ID account pagesign in to
- Get and enter the verification code
- Click on “Security”
- Click on “Turn off two-factor authentication”
- Choose 3 secret questions and enter the answers
- Enter the required information
- Completes when “Two-Factor Authentication Disabled” is displayed
* If “Turn Off Two Factor Authentication” is not displayed, the account is not subject to cancellation. In addition, since security cannot be guaranteed, please cancel at your own risk.
How to cancel two step verification
If you’re using Apple ID security with 2-Step Verification, you can revoke it the same way you revoke two-factor authentication.
What to do if you did not receive your two-factor verification code
Finally, we’ll show you what to do if you don’t receive the verification code required to log in, which is a common pitfall for two-factor authentication users.
Get the verification code again
If you haven’t received your two-factor verification code, you can redeem it.
However, since there is an upper limit on the number of times the confirmation code is issued, if you request it several times in a short period of time, the following note may be displayed.
・ The maximum number of verification code attempts has been reached. Please try again later.
It does not specify an upper limit on the number of attempts or how long you can wait to try again, but it is said that you can get it again after about 8 hours, so it is dangerous to get too much.
Improve device connection
The confirmation code is obtained from the Apple server, so it may not be possible to obtain it without a network environment.
However, if you just issued a confirmation code, you may be able to get it offline, so it’s convenient to remember that it may be possible to issue an iPhone without a SIM card or a Mac that’s not connected to the Internet.
Get the verification code manually
You can manually obtain a verification code for two-factor authentication. If you changed your iPhone model and have both before and after the model change, and you haven’t received the confirmation code for your new iPhone, try getting it manually.
- iPhone/iPad: Settings app > Username > Password & Security > Get Verification Code
- Mac: System Preferences > AppleID > Password & Security > Get Verification Code
- Apple Watch: Settings app > Username > Password & Security > Get Verification Code
As mentioned above, if you are signed in with the same Apple ID, you can also use a verification code obtained from another device.
You may be able to get the confirmation code even if you remove the SIM card, so if you didn’t receive it when you changed the model, try manually issuing it on your previous iPhone and inserting it.
If your trusted phone number changes
With two-factor authentication, if your trusted phone number changes (if you get a new phone number instead of changing your phone model), you need to change it.
If you have multiple trusted devices registered, this is not a big deal, but if you only have one device, you may not receive the verification code and you may not be able to get it.
Also, if the phone number has been changed, the password is unknown, and the device cannot be used due to some problem, then an account recovery procedure may be required.
If you can reset your password, you don’t need to recover your account, but if you can’t reset it, you will have to wait a few days to recover your account.
Please note that if you do not know your password when changing forms and need to restore your account, you may not be able to transfer your data.
If you don’t have a trusted device handy
This is a possible phenomenon for users who have switched from iPhone to Android, but it is also possible to not have a trusted device even if the Apple ID remains.
In this case, as long as your trusted phone number hasn’t changed, you can get a verification code if you really need it.
You can get it by phone or SMS, so click on “Did you receive the confirmation code?” And try to get it by phone or SMS.
What do you think? Once set up, two-factor authentication cannot be turned off.
Cancellation is only possible if you update unintentionally, but it’s hard to notice because there’s only a two-week grace period, and it’s hard to deal with it during that period.
We recommend that users who use security questions be careful not to inadvertently update after updating iOS.
