Why does WeChat Pay suddenly need a verification code?

The reasons for this situation include improving payment security and protecting users' property security.

1. Improve payment security: In order to prevent fraud, users need to enter their mobile phone number to obtain and verify SMS verification code during WeChat payment operation, so as to ensure that only the actual account holder can complete the payment process.

2. Protect the user's property: When the user's change payment amount exceeds a certain limit (such as 2000 yuan), the system will automatically send a verification code to the bank reserved mobile phone bound by the user to verify the security of the transaction.
