How to cancel the QQ token of mobile phone?

Open the phone token. There is an unbound QQ in it. Open it, and then you can unbind it by sending a short message to your mobile phone with QQ secret message ... I suggest not unbind it. The dynamic password of mobile phone token is quite secure. You can modify the QQ password with a computer, so you need to use a token. Set the automatic calibration time in the token and modify the QQ password with the token's dynamic password. I hope it can be adopted! thank you
