# Manage non-FIDO registrations

| URL: /nnlgateway/nnl/<tenantID>/reg Method: POST |
| --- |

---

Nok Nok provides operations to manage non-FIDO authentication methods like Email OTP, SMS OTP, Photo ID, and External Authentication. Using these operations you can retrieve a user's non-FIDO methods, delete their registered non-FIDO methods, suspend their non-FIDO methods, and resume any suspended methods. To manage FIDO authentication methods, use the operations, see [Manage FIDO Registrations](/dpoa/docs/s3suite94-manage-fido-registrations).

The following operations are available:

- [LIST_METHODS](/dpoa/docs/s3suite94-manage-non-fido-registrations#listmethods)
- [DELETE_METHODS](/dpoa/docs/s3suite94-manage-non-fido-registrations#deletemethods)
- [SUSPEND_METHODS](/dpoa/docs/s3suite94-manage-non-fido-registrations#suspendmethods)
- [RESUME_METHODS](/dpoa/docs/s3suite94-manage-non-fido-registrations#resumemethods)

## LIST_METHODS

Lists registered non-FIDO authentication method(s) for a user.

### Request

| **Attribute** | **Description** |
| --- | --- |
| operation | Required. The string LIST_METHODS. |
| callerOrigin | Required if a web app is sending the request and that app has a different origin than the Nok Nok API Server. A web origin is defined by the scheme (protocol), host (domain), and port of the URL used to access it. The API Server checks if this origin is listed in its origin allow list, if not, the request is rejected. See [My Web Apps Have a Different Origin](/dpoa/docs/s3suite94-my-web-client-apps-have-a-different-origin-than-the-api-server). |
| id | Optional. The correlation ID, a unique id that ties together different requests that comprise an operation. Alphanumeric string with a maximum length of 255 characters. No special characters are allowed. If not provided, the Server generates a unique id and returns it. |
| locale | Optional. The Server uses locale to tailor the end user's prompts to the language in the user’s profile. An IETF BCP 47 language tag string, like en-US. |
| sessionData | Required. An object containing the user's session information, may include the user name. See [SessionData](/dpoa/docs/s3suite94-nok-nok-data-types#sessiondata). |

### Response

The following attributes are always present in the JSON payload of the response.

| **Attribute** | **Description** |
| --- | --- |
| id | The unique id that correlates different requests comprising an operation. A Base64-URL encoded string. If id was sent in the request, the same id is returned. If not, a server-generated ID is returned. If id was provided in the REST payload but the server was unable to parse the payload, the value is unknown. |
| statusCode | Server-specific status code that reports the success or failure of this operation. Integer. See *Response Status Codes* below for the status and error codes. |

The following attributes are present in the response upon a successful operation (Server status of 4000).

| **Attribute** | **Description** |
| --- | --- |
| methods | A list of authentication methods objects that are registered to the user. Set<[Authentication Method](/dpoa/docs/s3suite94-nok-nok-data-types#authentication-method)>. The two fields listed in the rows below are of special note. The server returns a different set of fields under methods.data, depending on the type of authentication method. For example, Photo ID has a different set of fields than SMS OTP. For details, see [Data Field Contents by Authentication Method](/dpoa/docs/s3suite94-nok-nok-data-types#data-field-contents-by-authentication-method). |
| methods.data.identifier | Present when the authentication method is Email OTP, External Authentication, Photo ID, or SMS OTP. Has the following value: - Email OTP: user's email address that receives the passcode - External Auth: user name - Photo ID: ID type and hash of the content which could have come from an identification document such as a driver's license or passport. - SMS OTP: user's phone number that receives the passcode |
| methods.data.devices | Present for all non-FIDO authentication methods. Contains information about the devices where the method was registered. |
| methods.data.lastUsedTimeStamp | The time when the authentication method was last used. |

### Response Status Codes

The following are the descriptions of the Auth Server status codes returned by LIST_METHODS. Under certain circumstances, the API Server returns an unsuccessful HTTP status code. Examples include an invalid request or invalid session. You can find descriptions of these in [API Server Status Codes](/dpoa/docs/s3suite94-rest-api#api-server-status-codes).

| **Server Status Code** | **Description** | **Examples** |
| --- | --- | --- |
| 4000 | Ok. Operation completed. | Methods for the specified user were successfully fetched. |
| 4402 | Security exception | The facet ID sent by the client doesn't match the valid facet IDs configured on the Authentication Server. |
| 4404 | Internal Server error | Internal server error. Failed to read from the database. Failed to connect to the database. Failed to read required properties. |
| 4406 | Unacceptable content in the request. | One or more mandatory attributes are missing. |
| 4430 | User not found exception | User doesn't exist in the Server. |
