Generally, people in banks are here to achieve performance, so there is probably no problem.
Just remember that if you are asked for your account and password, it is probably a scam. If you apply for a credit card here in Beijing, you only need to fill out the application form and submit copies of your ID card and business card. You will not be asked for your account number and password. Even if you activate automatic repayment, you only need to fill in your account number and do not need to tell your password.
