  The '/sys/mfa/method/totp' endpoint focuses on managing TOTP MFA behaviors in Vault Enterprise.
---

## Configure TOTP MFA Method

This endpoint defines a MFA method of type TOTP.

| Method   | Path                           | Produces               |
| :------- | :----------------------------- | :--------------------- |
| `POST`   | `/sys/mfa/method/totp/:name`   | `204 (empty body)`     |

### Parameters

- `name` `(string: <required>)` – Name of the MFA method.

- `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.

## 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                                         | Produces                 |
| :------- | :------------------------------------------- | :----------------------- |
| `POST`   | `/sys/mfa/method/totp/:name/admin-generate`  | `200 application/json`   |

### Parameters

- `name` `(string: <required>)` - Name of the MFA method.

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

### Sample Payload

```json
{
  "entity_id":"4746fb81-028c-cd4e-026b-7dd18fe4c2f4"
}
```

### Sample Request

```

### Administratively Destroy TOTP MFA Secret

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

Note that in order to overwrite a secret on the entity, it is required to
explicitly delete the secret first. 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                                    | Produces               |
| :------- | :-------------------------------------- | :--------------------- |
| `POST`   | `/sys/mfa/method/:name/admin-destroy`   | `204 (empty body)`     |

### Parameters

- `name` `(string: <required>)` – Name of the MFA method.

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

### Sample Payload

```json
{
  "entity_id": "4746fb81-028c-cd4e-026b-7dd18fe4c2f4"
}
```

### Sample Request

```
