Why does WeChat transfer need a verification code?

Account protection, security verification, etc.

Account protection: WeChat may ask for a verification code to protect the user's account. If the system detects abnormal login or operation behavior, it may trigger the requirement of verification code to ensure that the user himself is conducting the transfer operation.

Security verification: Verification code is a common security measure, which is used to confirm the identity of users and ensure the security of transactions. By entering the verification code, you can prevent malicious software or automatic programs from unauthorized transmission.
