아이폰 공동인증서 저장 Pay with interest-free installments (feat. iPhone joint certificate)

So far, I’ve only used Android phones.
I’m using my iPhone for the first time this year.

The most inconvenient thing to use the iPhone was the public certificate (co-certificate), so let’s see how to copy the bank’s joint certificate from the iPhone.

Unlike PC and Android, iPhone can only be used by copying the joint certificate for each bank application from the PC homepage for all bank/brokerage applications.

Even the bank and credit card companies need to copy and export the joint certificate separately. 아이폰 공동인증서 저장

Please prepare enough time and a generous and relaxed mind to perform repetitive tasks ^^ 이베이스매뉴얼
* For iPhone security issues, all apps that require a joint certificate (banks, securities companies, etc.) must copy the joint certificate from each PC website to the iPhone.



1. When using a joint certificate (former public certificate)
If you want to use a joint certificate that is stored on the hard disk like the existing method, you need to store the certificate in your computer or mobile phone storage device.
How to copy iPhone joint certificate
1) Mobile phone -> PC
2) PC -> Mobile phone
3) Registration of certificates from other organizations
First, on your computer and mobile phone,
Access the Shinhan Bank website and Shinhan Bank application.

– Computer Shinhan Bank website:



1) Mobile phone -> PC copy
If your existing Android phone has a certificate,
You need to copy to your PC computer.
*If a joint certificate is already stored on your computer, please proceed to the next step.

– Computer Shinhan Bank website:

– Mobile phone Shinhansol application:

– Computer Shinhan Bank website:



2) PC-> Mobile phone copy
This is the process of copying the joint certificate from the computer to the Shinhan Bank application on the iPhone.

– Computer Shinhan Bank website:

– Mobile phone Shinhansol application:

– Computer Shinhan Bank website:
Enter the 8-digit number on the phone screen

3) Registration/Revocation of Certificates from Other Organizations
In my case, I did not register for a certificate from another institution because it was originally an accredited certificate issued by Shinhan Bank.
If it is an accredited certificate issued by another bank, additionally register the certificate of another institution.
In the case of a certificate issued by Shinhan Bank,
You can log in immediately without the need for authentication from other organizations.



2. When using a financial certificate
If you have ever been issued a financial certificate,
Because you only need to authenticate yourself, it is loaded from the cloud.
There is no need to store the certificate on your computer or mobile phone, and you can use it right away.
However, you can manage it in the bank app, but it is not used for login…


3. Private Certificate
(Naver, Payco, PASS, Toss, Kakao, etc.)
: Because banks use only two (joint certificate or financial certificate) certificates, certificates issued by private companies cannot be used in banking or securities company applications.




4. Use without a certificate
You can use the Shinhan Bank app without a certificate. (However, some functions are limited)

< Face ID / Pattern / Simple password >

There are three easy sign-in methods to choose from, and I tried Face ID among them.
If you do not have a certificate on your iPhone, you can do basic work with simple login



Copying the iPhone joint certificate is cumbersome and inconvenient🥲
However, if you have already purchased an iPhone and started using it,
I recommend that you take a day and access the websites of all financial and securities companies installed on your mobile phone with your PC and run the task of copying the joint certificate with your iPhone…!


I will finish by leaving a list of representative banks so that we do not forget 🙂
