After the prescriber is granted EPCS privileges, she can e-prescribe controlled substances.
In addition to identity proofing and two-factor authentication (TFA), the DEA requires that logical access controls are established so that only authorized providers can electronically prescribe controlled substances. For a description of all logical access control operations and rules, go to the EPCS Logical Access Controls help page.
After you have selected your two EPCS administrators, these administrators must grant and finalize EPCS privileges to each prescriber.
Two-factor Authentication
The DEA requires strict security measures be in place to verify the prescribing provider’s identity. Therefore, two-factor authentication is mandated every time a controlled substance is electronically prescribed. TFA is also performed when finalizing a grant, revoke, or regrant of EPCS privileges.
- The Universal ID password from Verizon Universal Identity Services (VUIS) that was created during the identity proofing process.
- The autogenerated one-time passcode from VUIS. Tip: If the prescriber is using the Verizon app, open the app before performing TFA.
Grant
The prescriber cannot grant EPCS privileges to himself. He must have another administrator grant him privileges.

- Navigate to the EPCS Status page (Admin > e-Rx EPCS Registration > click
) as the first administrator (Mary Cormier).
- Click Setup.
- You are navigated to the EPCS Setup page.

- Sign in as the first administrator and then scroll down to the Authorize EPCS Privileges table.
- Click Select for the doctor that you want to grant privileges for.
Finalize Grant
TFA is required to finalize the grant of EPCS privileges; therefore, only an EPCS-activated prescriber can finalize. The prescriber who is being granted EPCS privileges can finalize himself since he did not perform the grant action.

- The prescriber who has been granted privileges moves down under Finalize EPCS Authorized Privileges. The second administrator must now finalize the grant.
- Any EPCS administrator other than the administrator who granted EPCS privileges (Mary Cormier) can perform the finalize, including the prescriber (Kenneth Moon) being granted EPCS access.
- Navigate (as the second administrator – Kenneth Moon) to the EPCS Setup page.
- Click Select.

- If you are using the Verizon app to receive the one-time passcode, open the app if you have not done so already.
- Click Get one time passcode.

- If using the app, enter the second administrator’s Universal ID password and the autogenerated one-time passcode.
- If using text or voice message, enter the Universal ID password, select Text or Voice from the menu and click Text Me or Call Me, respectively. When you receive the one-time passcode, enter it in the field provided.
- Click Continue.

- You have finalized the grant.
- To verify the finalize was performed successfully, check the logical access audit log.
