The mobile phone is bound to qq, how to change the password by SMS?

it must be a set secret mobile phone, not a mobile phone binding (small silver mobile phone on the customer service side). Edit the short message "GM's new password for your QQ account" (for example: gm123456 XinMiMa) with a secret mobile phone, and send it to 16575582381 for mobile users, 1661799 for CDMA users and Unicom users (the sending instructions are different for different mobile phones).

please log in directly → change password → select "secure mobile phone by secret" → click "Next", and send relevant short messages as prompted to change password. Note: Gm instruction is case-insensitive, and gm, gM, GM and GM are all the same; The password consists of 6-16 characters, and cannot be a pure number with less than 9 digits. The password cannot contain spaces, and the letters are case-sensitive (for example, xinmima is different from XinMiMa).
