Credit cards can be set without passwords, but the following items should be noted:

1. In international practice, it is very common to use credit cards abroad and use my signature instead of password. Because the password can be stolen but the signature is unique, foreigners are used to using credit cards in the form of signatures.

Second, when applying for a credit card in China, you can choose a signature instead of a password on the application form, but the general bank will prompt you to set a password, because it is customary to use a credit card with a password in China. When using credit cards in banks, self-service banks, shopping malls, hotels, supermarkets, etc., the staff will prompt to use the password. Using the card only by signature may lead to failure to check, which may lead to great risks in the use of the card.

To sum up, although credit cards can be signed without a password, in the market environment of China, it is recommended that you set a password.
