A session is a temporary, continuous period of authenticated interaction between a user and a system, beginning when credentials are accepted and ending on logout, disconnection, invalidation, or expiration after a set timeout. In platforms such as Namazu Elements Core, creating a session returns a session token (or secret) tied to the user and, where applicable, a selected profile or application, which clients then include with subsequent API requests so identity, permissions, and state persist until that session expires or is revoked.
