For account security, when you log in to WeChat on a new device for the first time, you must enter your account ID and password or your mobile number and verification code. After this step, the device will prompt you to complete a second verification. The available options are as follows:
- Use your previous device to open the WeChat app and scan the QR code displayed on the new device.
- Log in using your account ID and password, or your mobile number and verification code.
- Use your linked email address to receive a verification code and log in.
- Invite friends to assist with verification. Ask two frequent contacts to send a verification code to your account, then refresh to check the result.
Once you complete any of the above verification methods, you will be able to log in successfully.
