I didn't send a text message. Is Taobao green card safe after use? How to ensure safety?

You mean bound to AliPay.

As long as you don't reveal all the passwords,

Including the withdrawal password of the card. Alipay's payment password is definitely safe.

* * * Note the following:

1.

Never use your above two passwords on computers in public places at any time.

Avoid being stolen or recorded by others,

Especially in Internet cafes, many people don't know many softwares for recording keyboards.

So the number was stolen and the password was stolen.

2.

Alipay cartoon application certificate,

Set the payment password, protect it with password, please.

3.

It is best to open SMS notification on Alipay.

It costs nothing,

Operations on Alipay can only be used through password verification.

Safest.

4.

When you say no SMS notification, you mean no SMS notification in online banking and no SMS notification in banks.

It costs money. It doesn't matter if you don't open it, as long as you open Alipay or protect your password.
