Credit cards generally have two passwords. You can directly call the credit card customer service to apply for modification, and the customer service can modify it after confirming the identity:

1. Inquiry password (telephone password): used for online banking login or telephone inquiry.

2. Transaction password (bank password): used for credit card consumption or ATM cash withdrawal.

Both passwords can be changed directly by calling credit card customer service, or you can bring relevant certificates to the bank to change them.

Precautions for changing credit card password when using password:

1, don't use money or letters with obvious characteristics as passwords. Such as account number, birthday, ID number, telephone number, and single number and duplicate number.

2. Different accounts use different passwords. In order to avoid being guessed all the passwords at once.

3. Don't throw away statements, receipts and transaction documents. Usually it says personal information on it. Tear them up thoroughly and make sure that the personal information on them has been destroyed before throwing them away.

If you are used to recording the password on paper, you must keep it well, don't lose it, don't put it in a place where others can easily find it, and don't write it in your diary. Now there are privacy safes, password books and so on. In the mobile APP, you can record your important password, which is relatively reliable and easy to use.

5. When the computer logs into your bank account, don't set a save password, and don't set an automatic login, especially for the computer at work, to avoid being found and recorded by others. When using online banking, don't use it in public places such as Internet cafes and libraries, so as to avoid being infected with viruses and causing the account to be stolen.
