---

## Configure TOTP MFA Method

This endpoint defines an MFA method of type TOTP.

| Method | Path                            |
| :----- | :------------------------------ |
| `POST` | `/identity/mfa/method/totp/:method_id` |

### Parameters

- `method_id` `(string: "")` - Optional UUID to specify if updating an existing method.

- `method_name` `(string)` - The unique name identifier for this MFA method. Supported from Vault 1.13.0.

- `issuer` `(string: <required>)` - The name of the key's issuing organization.

- `period` `(int or duration format string: 30)` - The length of time used to generate a counter for the TOTP token calculation.

- `key_size` `(int: 20)` – Specifies the size in bytes of the generated key.

- `qr_size` `(int: 200)` - The pixel size of the generated square QR code.

- `algorithm` `(string: "SHA1")` – Specifies the hashing algorithm used to generate the TOTP code. Options include "SHA1", "SHA256" and "SHA512".

- `digits` `(int: 6)` - The number of digits in the generated TOTP token. This value can either be 6 or 8.

- `skew` `(int: 1)` - The number of delay periods that are allowed when validating a TOTP token. This value can either be 0 or 1.

- `max_validation_attempts` `(int: 5)` - The maximum number of consecutive failed validation attempts.

## Administratively Generate a TOTP MFA Secret

This endpoint can be used to generate a TOTP MFA secret. Unlike the `generate`
API which stores the generated secret on the entity ID of the calling token,
the `admin-generate` API stores the generated secret on the given entity ID.

| Method | Path                                       |
| :----- | :----------------------------------------- |
| `POST` | `/identity/mfa/method/totp/admin-generate` |

### Parameters

- `method_id` `(string: <required>)` - UUID of the MFA method.

- `entity_id` `(string: <required>)` - Entity ID on which the generated secret
  needs to get stored.

### Sample Payload

```json
{
  "method_id": "4746fb81-028c-cd4e-026b-7dd18fe4c2f4",
  "entity_id": "9189f7fd-e3f5-436b-a835-cb14864b1e01"
}
```

### Sample Request

### Administratively Destroy TOTP MFA Secret

This endpoint deletes a TOTP MFA secret from the given entity ID.

To overwrite a secret on the entity,
explicitly deleting the secret first is required. This API can be used to delete the secret
and the `generate` or `admin-generate` APIs should be used to regenerate a new
secret.

| Method | Path                                      |
| :----- | :---------------------------------------- |
| `POST` | `/identity/mfa/method/totp/admin-destroy` |

### Parameters

- `method_id` `(string: <required>)` - UUID of the MFA method.

- `entity_id` `(string: <required>)` - Entity ID from which the MFA secret
  should be removed.

### Sample Payload

```json
{
  "method_id": "4746fb81-028c-cd4e-026b-7dd18fe4c2f4",
  "entity_id": "9189f7fd-e3f5-436b-a835-cb14864b1e01"
}
```

### Sample Request

```shell-session

    --header "X-Vault-Token: ..." \
    --request POST \
    --data @payload.json \
    http://127.0.0.1:8200/v1/identity/mfa/method/totp/admin-destroy
