Let’s find out how to find and change the password for the joint certificate/authorized certificate in KICA.
So far, accredited certificates are widely used in many places. It was revoked some time ago and is being referred to as a joint certificate under a new name. Several private certificates have emerged and are being used in various ways, but it still takes time to establish itself, and it is not known which certificates will become popular. In such a situation, I think that public certificates (currently joint certificates) have continued as before in terms of their use, such as banking and personal authentication.
If the public certificate is not used often, the password is often forgotten. In case of confusion, if you try to enter the password a few times, the use of the certificate may be stopped due to the number of password errors exceeded. If you can’t remember the password for the certificate, there is a way to check it by entering the password an unlimited number of times.
You’re just entering a predictable password. Even if you do this, if you cannot find the password, you have no choice but to reissue the certificate.

Following the bonus or negative year-end settlement in 13 months, the deadline for filing tax returns in May is approaching. We all know that login is essential in this process. Unlike in the past, where you had to do one thing unconditionally, these days, various methods are allowed, which makes it a lot more convenient. There are several simple login methods supported, but among them, today, the KakaoTalk joint certificate issuance method that is simpler than a bank joint or financial certificate and can be usefully used in Hometax, Sontax, Witax, Government 24, etc. Let’s see together how to find my password.



Issuing Kakao Talk Joint Certificate


First, turn on the app, go to the ①<ㆍㆍㆍ> tab at the bottom right corner, and then go to ② Wallet. Then you will see the <Issue> button at the top. Just click on this part. If you see the update button even though you have already created it, it is recommended to do it for security.




Before starting, it is basically possible from version 9.6.0 or later of KakaoTalk, and if the phone number is an overseas number, uses KakaoTalk without an account, or the account status is abnormal, when the service is under maintenance, children under 14 years of age and their own mobile phone number If you do not have a bank account, you may see a screen indicating that the issuance could not be issued or that it could not be issued.




I had previously received a KakaoTalk joint certificate, and as shown above, it was a case that needed an <update>, so I proceeded as it is. The process for both new and update is the same, so you just have to follow them together. When you start, you will be prompted to agree to the terms and conditions. All of these are mandatory, so check the top and move on to the next, fill in the blanks and enter the verification code sent to you by text.




Then, after the mobile phone number, the second authentication is carried out. In this case, you must enter the bank name and account number in your name. Then write in the blanks a four-digit word that is sent along with 1 won to the bank account I wrote down. For reference, it is 1 won, so there is a high probability that you will not receive a separate notification, so it is faster to go in and see it yourself 🙂




If you have entered it correctly, you can now enter the 6-digit number to be used on the KakaoTalk my password screen and you are done. Depending on the settings, even biometric authentication may be rough, but issuance is completed as soon as a number is entered. So simple, right? In addition, as with general public certificates, there is an expiration date. It is about 3 years, but if you are curious about the exact date, you can check it by going to management.


It’s easy to do


First, select the KakaoTalk icon when selecting a method on a site that supports simple authentication. Then a message is sent from the wallet. At this time, click the <Authenticate> button, check the agreement, and then enter your KakaoTalk my password or perform fingerprint recognition and you are done. History, etc. can be viewed through the history view, and it is also used for identity authentication when attempting to log in from an unregistered PC Kakao Talk or other device, and when using the Talk Drawer function.


Is KakaoTalk joint certificate possible on PC?


Because it is convenient to use, there may be some people who want to use it on a computer as well. It is possible to import from outside, but unfortunately it is not possible to export from mobile KakaoTalk to PC. Therefore, please remember that it can only be used on mobile and can be processed quickly when a smartphone is nearby during authentication 🙂

Find my password on Kakao Talk


There are 3 types of passwords only within the KakaoTalk service, so unless you set them uniformly, you may be confused or forgotten. In that case, please do not be annoyed and follow the method I am going to tell you from now on. As in making it, go to the tab at the bottom right corner and enter the shape of a <gear> this time.




Then you will enter the settings window. From here, go to <Personal/Security> and click <Manage My Password → Change> in the middle. i like easy
