# Activate MFA User Device

##

```none
POST {{apiPath}}/v1/environments/{{envID}}/users/{{userID}}/devices/{{deviceID}}
```

Devices with a `status` of `ACTIVATION_REQUIRED` are activated using a valid one-time password (OTP). The OTP is sent to the phone number or email address specified in the device resource's properties.

The sample shows the `POST {{apiPath}}/v1/environments/{{envID}}/users/{{userID}}/devices/{{deviceID}}` operation to activate the device specified in the request URL. This operation uses the `application/vnd.pingidentity.device.activate+json` custom content type in the request header to specify the activation action.

When the activation action is completed successfully, the response returns a `200 OK` message and the device `status` property is changed to `ACTIVE`.

### Prerequisites

* Refer to [MFA Devices](#mfa-devices) for important overview information.

* [Create a user](/pingone/platform/v1/api/#post-create-user) to get a `{{userID}}` for the endpoint. For more information, refer to [Users](/pingone/platform/v1/api/#users).

* Use [Read All MFA User Devices](#get-read-all-mfa-user-devices) to retrieve a list of all device resources associated with the specified user and select the specific `deviceID` for the endpoint. For more information, refer to [MFA Devices](#mfa-devices).
