MFA for Electronic Prescribing for Controlled Substances (ePCS)

The guide below outlines the setup process to install the Okta Multifactor Authentication (MFA) provider for ePCS.

Electronic Prescribing for Controlled Substances (ePCS) eliminates paper prescriptions entirely by allowing clinical prescribers to electronically write prescriptions for controlled substances. It also permits pharmacies to receive, dispense and archive these e-prescriptions.

ePCS also creates new “Identity Proofing” responsibilities for vendors, prescribers, and pharmacies by requiring two-factor authentication, more robust audit trails and strict auditing procedures in order to comply with the Interim Final Rule regulating ePCS of the U.S. Drug Enforcement Administration (DEA).

The following diagram shows the information flow.



  • User:
    • Must exist in Okta
    • Must be assigned the Epic Hyperspace app in Okta
    • Must enroll in MFA prior to performing a ePCS transaction.
  • Administrator must configure Citrix servers to allow users write access to the log folder.
    Typically C:\Program Files (x86)\Okta\OktaHyperspaceLoginDevice\logs

There are five parts to the configuration, including a pre-configuration step.
