A method is provided for accessing information in a content management system including a library server for generating non-transferable access tokens and an object server for storing objects to which access may be requested by a client user. Enhanced security is achieved by generating nontransferable access tokens which can be used by a particular client user to access a particular data object in the object server. However, should the token be transferred to a user other then the client user for which the token was generated, the system will not permit access to the object.
