Described herein is a platform and method for providing multi-level authentication by an onboard system in relation to a transaction. In response to receiving information related to a transaction, one or more authentication policies may be identified and provided to an onboard system associated with the transaction. The authentication policies may be executed by the onboard system to generate a result set indicating a pass/fail for each authentication policy. Once the result set has been generated, success actions and/or failure actions associated with each authentication policy may be executed in accordance with the generated result set.
