Does WeChat need face recognition to change the mobile phone number?

Wechat needs face recognition to change the mobile phone number. This is because face recognition technology can effectively verify the user's identity and ensure the legal and safe operation of changing the mobile phone number. By using face recognition technology, WeChat can perform real-time authentication in the process of changing the mobile phone number to prevent others from fraudulently using their accounts for malicious operations.

Face recognition technology is a biometric identification technology based on facial features for identity verification. It can confirm whether the user's identity matches by analyzing and comparing the feature points, contours and textures of the face. Compared with other authentication methods, such as password or SMS verification code, face recognition has higher security and reliability.

Extended content: With the continuous development of science and technology, face recognition technology has been widely used in various fields. In addition to identity verification, face recognition can also be applied to face payment, access control system, security monitoring and other fields. The development of face recognition technology not only improves the security, but also provides users with a more convenient and quick operation experience. However, it is followed by concerns about personal privacy and information security. It is necessary to ensure the legal and compliant use of face recognition technology and ensure that users' personal information is properly protected.
