Let’s find out two ways to find the password for the joint certificate. Since the joint certificate (formerly public certificate) can be used for a validity period of one year after it is issued, the password can sometimes be lost or forgotten, but if the password of the joint certificate is wrong five times, it may vary depending on the certificate, but it can no longer be used. However, using this method, it is possible to find the password of the joint certificate without errors even if you make consecutive mistakes in off-duty numbers.공동인증서 비밀번호 찾기

How do I find the certificate password if I lose it?
The common certificate password (password) cannot be verified anywhere because it is encrypted so that no one else can know it for security.
However, there is a method that can be checked regardless of the number of times a password is entered, so if you do not know the method or the password, please proceed with the reissue.
What are the precautions when entering a certificate password?
The certificate password is no less than 10 characters long and contains one or more English characters, numbers, and special characters. Therefore, please understand the rules and look for passwords.
