System and method for re-authentication of asynchronous messaging

A system and method are presented for the re-authentication of asynchronous messaging, specifically within enterprise to consumer communications. A third-party enterprise messaging server may be used as a conduit for a messaging service allowing for customer interaction with a business. The messaging server can append a re-authentication process for customers once a customer has been authenticated by the enterprise. Each time a customer resumes an interaction exceeding a timeout threshold, the messaging server invokes its re-authentication process. Lapsed interactions may be treated as continuous without having the customer re-authenticate through the enterprise specific authentication.
