# Enable users to enter an OTP with their username in MS-CHAP v2, or EAP-MSCHAPv2 mode

PingOne RADIUS Gateway with MS-CHAP v2 or EAP-MSCHAPv2 only works in no-challenge mode.

## About this task

Your users can enter a one-time passcode (OTP) with their username when signing on in no-challenge mode. To do this, a custom separator should be added to the Network Policy Server (NPS). The same custom separator must also be configured in the DaVinci flow. Learn more in the [PingOne RADIUS gateway connector](https://docs.pingidentity.com/connectors/p1_radius_gateway_connector.html) documentation.

For example, adding a comma separator enables the user to enter the OTP in the format` <username>,OTP`. For user `John`, OTP `123456` is entered as `John,123456`.

To configure the NPS to enable users to enter an OTP together with their username:

## Steps

1. Sign on to the Windows server and open the **Network Policy Server** (NPS) configuration window.

2. In the **NPS** tree, under **Policies** click **Connection Request Policies**.

   * **Replace with**: `$1`
