I didn't request a SMS verification code, why am I receiving a WeChat SMS verification code?
20 Nov 2025
If you can still log in to your account normally, but have recently received a SMS verification code, it means that your WeChat account is still safe, but someone else is trying to log in to your account. As a security protection measure for all users, when someone attempts to log in to WeChat from a new device, the system will require SMS verification to better protect the security of your account. If you have received the SMS verification code from us but have not logged into WeChat from a new device recently, someone else may have obtained your WeChat password. Please do not disclose any SMS verification codes you receive to others and change your password immediately. It needs to be emphasized again that since logging in from a new device must be verified through SMS, your WeChat account is still safe at present; but we strongly recommend that you change your password as soon as possible
