Forgot how to retrieve the online registration password?

When you say online registration, do you use a local medical insurance card or a nationwide health road reservation card? If it is a medical insurance card, you need to go to the local medical insurance service center and modify it with your ID card (the local medical insurance card seems to have no password). If it is a health road registration reservation card, log on to the health road website or call the national unified customer service phone to modify it. I hope this helps.
