A token value may consist of a set of requirements that the requester must satisfy before the requested content is delivered. These requirements may be mixed and matched as desired. Adding, modifying, or removing requirements simply involves generating another unique token. Clients that use the older token will still be able to access your content as long as they still meet its requirements and the encryption key used to generate it is still active.
Tokens can be specific to a particular folder or asset. Take advantage of this capability to prevent a token from being reused to access other protected content.

As previously noted, a token value is required for the delivery of content for which Token-Based Authentication has been applied. This token value may either be the same for all content or the set of requirements may vary according to the content being requested.
