# auth tune

The `auth tune` command tunes the configuration options for the auth method at
the given PATH. **The argument corresponds to the PATH where the auth method is
enabled, not the TYPE!**

## Examples

Before tuning the auth method configuration, view the current configuration of the
auth method enabled at "github/".

```shell-session
$ vault read sys/auth/github/tune
Key                  Value
---                  -----
default_lease_ttl    768h
description          n/a
force_no_cache       false
max_lease_ttl        768h
token_type           default-service
```

The default lease for the auth method enabled at "github/" is currently set to
768 hours. Tune this value to 72 hours.

```shell-session
$ vault auth tune -default-lease-ttl=72h github/
Success! Tuned the auth method at: github/
```

You can specify multiple audit non-hmac request keys.

```shell-session
$ vault auth tune -audit-non-hmac-request-keys=value1 -audit-non-hmac-request-keys=value2 github/
Success! Tuned the auth method at: github/
```

## Usage

The following flags are available in addition to the [standard set of
flags](/docs/commands) included on all commands.

- `-allowed-response-headers` `(string: "")` - response header values that the auth
  method will be allowed to set.

- `-audit-non-hmac-request-keys` `(string: "")` - Key that will not be HMAC'd
  by audit devices in the request data object. Note that multiple keys may be
  specified by providing this option multiple times, each time with 1 key.

- `-audit-non-hmac-response-keys` `(string: "")` - Key that will not be HMAC'd
  by audit devices in the response data object. Note that multiple keys may be
  specified by providing this option multiple times, each time with 1 key.

- `-default-lease-ttl` `(duration: "")` - The default lease TTL for this auth
  method. If unspecified, this defaults to the Vault server's globally
  configured default lease TTL, or a previously configured value for the auth
  method.

- `-description` `(string: "")` - Specifies the description of the auth method.
  This overrides the current stored value, if any.

- `-listing-visibility` `(string: "")` - The flag to toggle whether to show the
  mount in the UI-specific listing endpoint. Valid values are `"unauth"` or `"hidden"`.
  Passing empty string leaves the current setting unchanged.

- `-max-lease-ttl` `(duration: "")` - The maximum lease TTL for this auth
  method. If unspecified, this defaults to the Vault server's globally
  configured [maximum lease TTL](/docs/configuration#max_lease_ttl), or a
  previously configured value for the auth method. This value is allowed to
  override the server's global max TTL; it can be longer or shorter.

- `-passthrough-request-headers` `(string: "")` - request header values that will
  be sent to the auth method. Note that multiple keys may be
  specified by providing this option multiple times, each time with 1 key.

- `-token-type` `(string: "")` - Specifies the type of tokens that should be
  returned by the auth method.
