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

# `/sys/mfa`

~> **Enterprise Only** – These endpoints require Vault Enterprise.

## Configure MFA Method

This endpoint defines a specific `type` of MFA method. Once set, the `type` of the MFA
method is immutable.

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

### Parameters

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

- `type` `(string: <required>)` - Type of the MFA method. Currently it only
  supports `totp`.

#### Type `totp` Parameters

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

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

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

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

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

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

- `totp_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 Destroy MFA Secret

This endpoint deletes an MFA secret from the given entity ID. This needs to be
called if an existing secret in an entity needs to be overwritten by calling
`generate` or `admin-generate` APIs.

| 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.
