A dynamic instruction processing method performed by a dynamic instruction processing apparatus and used for a terminal, wherein the terminal comprises multiple operating systems, and the dynamic instruction processing method comprises: when a dynamic instruction acquisition request sent by a specified application program in a specified operating system among the multiple operating systems is received, generating a target dynamic instruction; and acquiring the generated target dynamic instruction, and performing a corresponding authentication operation by using the target dynamic instruction, further comprising: when the specified application program in the specified operating system is enabled and login is carried out through a user identity account, prompting the user of the terminal to input the dynamic instruction to perform the corresponding authentication operation, the corresponding authentication operation being authentication of the user of the terminal; and when the terminal is detected to prompt the user to input the dynamic instruction, controlling the specified operating system to send the dynamic instruction acquisition request corresponding to the user identity account of the specified application program, characterized in that before the dynamic instruction is generated, the dynamic instruction processing method further comprises: when the dynamic instruction acquisition request is received, determining whether the user identity account of the specified application program corresponding to the dynamic instruction acquisition request has the permission to acquire the dynamic instruction; and when the determination result is yes, generating the target dynamic instruction corresponding to the user identity account of the specified application program, and when the determination result is no, not generating the target dynamic instruction. when a dynamic instruction acquisition request sent by a specified application program in a specified operating system among the multiple operating systems is received, generating a target dynamic instruction; and acquiring the generated target dynamic instruction, and performing a corresponding authentication operation by using the target dynamic instruction, further comprising: when the specified application program in the specified operating system is enabled and login is carried out through a user identity account, prompting the user of the terminal to input the dynamic instruction to perform the corresponding authentication operation, the corresponding authentication operation being authentication of the user of the terminal;
