註意:如果是秘密安全問題或者秘密安全手機，手機qq不能設置。如果要設置或修改，需要用電腦登錄qq，在安全中心設置。
擴展數據:
其實不管是密碼被盜還是忘記，壹個簡單實用的方法就是申請QQ密碼保護。點擊上面的鏈接，輸入QQ賬號、QQ密碼、驗證字符，按照提示填寫所有信息(註意，壹定要記住自己填寫的信息，壹定要記住以後找回密碼需要的信息，尤其是身份證號。
部分郵箱無法接收QQ郵件，建議使用QQ郵箱)。密碼保護功能可以確保您的QQ號碼更加安全，並在您的密碼出現問題時，幫助您更加方便快捷地找回新密碼。但目前新申請的號碼壹般都需要填寫二代密碼來保護數據，所以壹般的9位數字都是有二代密碼保護的，不需要單獨申請。
