Method and device for centralized management of dynamic instance identity and access

The invention discloses a method and a device for centralized management of dynamic instance identity and access. The method comprises the following steps: defining roles and authorities; when the dynamic instance is generated, the token management module automatically distributes tokens and registers the tokens to the token management module, and the token management module endows the dynamic instance with a unique non-human identity; the dynamic instance uses the non-human identity of the dynamic instance, authentication is carried out on the password insurance library through the authentication module, and password insurance can be verified on the non-human identity management module; and the auditing module records role definition and authority management of the dynamic instance, dynamically gives a non-human identity and an access privilege account process, and forms non-tampered log information. According to the invention, managers of enterprises or organizations can better manage the dynamic instances
