Basically tell others all the passwords, and they can only help you "sell" or "buy" the fund. Funds are different from stocks. Manipulating your stock account allows you to take orders for him, but the fund account can't, so even if you know your fund-related password, it won't do anyone any good.

In addition, various commercial banks have provided many security measures. As long as your online banking login name, password and digital certificate are well kept, you don't need to worry.

For most people, it is a relatively simple and effective security measure to buy the UsbKey of the bank (ICBC is called U shield and CCB is called UK) and modify the default password. In addition, if you directly invest in the fund on the fund company's website, it is also a good security measure to enter the password with the soft keyboard and the mouse.
