Provided is a token management method in which an information processing system configured by a plurality of computers including an arithmetic device and a storage device and comprising a token registration unit, a user management unit, a token management unit, a policy management unit, and a lifecycle management unit is used to deploy a token on the basis of a request from an end user. The token registration unit registers a test result of a token program, an electronic signature as a confirmation evidence, and a hash into the storage device as repository information. The user management unit records agreement of the end user for delegation of token operation to a virtual organization as a trail, and registers the agreement into the storage device as user information management information. The token management unit records agreement of the end user for token deployment as a trail, and registers the agreement into the storage device as token information management information. The policy management unit updates the policy definition registered in the storage device such that a signature of the virtual organization to which the operation has been delegated is necessary for the token deployment. When the lifecycle management unit receives a deployment request for a token, the lifecycle management unit refers to the policy definition, and deploys the token when the deployment request satisfies the policy definition.
