Bank cards can change their passwords on atm machines. Here are four ways to change your password:

1. Counter modification: Cardholders need to bring their ID cards and bank cards to the corresponding bank counters for modification.

2. Modify by machine: Cardholders can modify passwords on self-service deposit machines, ATMs and multi-function terminals according to the prompts on the machine.

3. Online banking modification: You can log in to your online banking, enter the login password, and then select the account service to modify it.

4. Telephone modification: You can call ICBC customer service directly and select the settings manually. After entering the initial password or the original password, the settings will generally take effect within three working days.

The reason why the bank card password can be modified in the above three ways without using a physical card is precisely because the issuing bank has achieved the effect of customer identification through electronic certificate, electronic signature or manual identity confirmation, whether it is online banking, mobile banking or customer service telephone.

Because both online banking and mobile banking have real-name authentication user names and login passwords, their operation behaviors are regarded as their own behaviors, similar to online verification of counter ID cards and photo archiving.

The network remote operation of bank card password modification inadvertently brings great convenience to cardholders and saves the trouble of queuing.

But it will also bring more storage responsibilities to customers, and the most direct thing is how to ensure the security of mobile phones.

Therefore, if your mobile phone is lost, you should report the loss of your bank card and mobile phone card as soon as possible to prevent risks in time.
