How to untie qq mobile phone number?

Qq can't unbind the mobile phone number, only unbind it. Modifying the binding is very simple, then click the mobile phone number option in QQ settings and press the system prompt to complete it.

Some QQ have forgotten their account passwords because they have not been used for a long time, but these QQ are still bound to the mobile phone number, occupying the bound quota. How to change the binding steps are as follows:
