Embodiments of the invention are directed to a system, method, or computer program product for providing elastic authentication based on a continuum of elastic authentication credentials. In particular, the invention provides a secure platform for authorization of a user activity at least partly based on validation of the continuum of elastic authentication credentials comprising cumulative tiered elastic authentication tokens captured during an extended time period prior to initiation of a user activity. The invention provides a novel method for capturing multiple elastic authentication tokens, for example, arbitrarily during an extended time period preceding a user activity, and validating the cumulative elastic authentication tokens at a time during or after initiation of the user activity. Another aspect of the invention is directed to mitigating interception of authentication credentials by employing the elastic authentication tokens captured/received using multiple communication channels over various time periods preceding the user activity.
