At present, social security cards, like bank cards and membership cards, have become common cards in residents' daily life. However, most citizens' social security cards do not have passwords, and some citizens don't even know that social security cards can have passwords. Although our social security card has ID number and photo, the clerk will not check it when you go to the pharmacy to buy medicine, and you don't need to show other documents. Considering the convenience of use, the social security card has no initial password. After setting the password for the social security card, the waiting time for hospital registration may be extended. If you forget your password, it will bring inconvenience to the insured, especially the elderly and people with sudden illness. If the insured needs to set or modify the password, he can add the password through the hotline 12333, or bring his ID card and social security card to the medical insurance center in the jurisdiction for on-site handling. If the password is lost, please bring your valid ID card to the service window of the county employment agency or the county social security center to check the password.
