Why does Alipay transfer need a mobile phone verification code?

To transfer money with Alipay, you need to bind your mobile phone to receive the verification code, but not every transaction needs to receive the verification code. If the charging SMS verification service is enabled, you need to enter the mobile phone verification code for each expenditure (without checking the transfer and withdrawal of Yu 'ebao).

Deputy Director of Communication Law Research Center of China University of Political Science and Law said that SMS verification code is the core of account security, and it is a key to ensure the security of funds.

Some banks also send text messages in their own banks. When the bank SMS and SMS verification services are duplicated, only the bank SMS is sent. Such as Bank of Communications, Shanghai Pudong Development Bank and some postal banks.

The system will perform a security check. From the security point of view, it may randomly ask for the mobile phone verification code to improve the security of the account. The above rules are not applicable to wireless terminals, which have their own security inspection rules.

After logging into the account through SMS verification code, criminals can obtain the user's express address, consumption records, address book and other private information, and can also "collect" the user's name, ID card and bank card number through "bumping into the library" and "social worker" to carry out activities such as fund theft, telecom fraud and extortion.

In addition to being "peeped", there are many ways for SMS verification code to be leaked. Some users click on illegal links, and mobile phones are installed with monitoring Trojans; Some criminals disguise bank customer service and directly ask for verification code content; There are also spies in the operators, who take the initiative to leak secrets and collude inside and outside. In addition, although the original intention of SMS cloud synchronization, automatic filling in verification code and other functions is convenient for users, it may also be used by criminals.
