/sys/auth

The /sys/auth endpoint is used to list, create, update, and delete auth methods. Auth methods convert user or machine-supplied information into a token which can be used for all future requests.

List Auth Methods

This endpoint lists all enabled auth methods.

Method	Path
`GET`	`/sys/auth`

Sample Request

$ curl \
    --header "X-Vault-Token: ..." \
    http://127.0.0.1:8200/v1/sys/auth

Sample Response

{
  "github/": {
    "type": "github",
    "description": "GitHub auth"
  },
  "token/": {
    "config": {
      "default_lease_ttl": 0,
      "max_lease_ttl": 0
    },
    "description": "token based credentials",
    "type": "token"
  }
}

Enable Auth Method

This endpoint enables a new auth method. After enabling, the auth method can be accessed and configured via the auth path specified as part of the URL. This auth path will be nested under the auth prefix.

For example, enable the "foo" auth method will make it accessible at /auth/foo.

sudo required – This endpoint requires sudo capability in addition to any path-specific capabilities.

Method	Path
`POST`	`/sys/auth/:path`

Parameters

path (string: <required>) – Specifies the path in which to enable the auth method. This is part of the request URL.
NOTE: Use ASCII printable characters to specify the desired path.
description (string: "") – Specifies a human-friendly description of the auth method.
type (string: <required>) – Specifies the name of the authentication method type, such as "github" or "token".
config (map<string|string>: nil) – Specifies configuration options for this auth method. These are the possible values:
- default_lease_ttl (string: "") - The default lease duration, specified as a string duration like "5s" or "30m".
- max_lease_ttl (string: "") - The maximum lease duration, specified as a string duration like "5s" or "30m".
- audit_non_hmac_request_keys (array: []) - List of keys that will not be HMAC'd by audit devices in the request data object.
- audit_non_hmac_response_keys (array: []) - List of keys that will not be HMAC'd by audit devices in the response data object.
- listing_visibility (string: "") - Specifies whether to show this mount in the UI-specific listing endpoint.
- passthrough_request_headers (array: []) - List of headers to whitelist and pass from the request to the plugin.
- allowed_response_headers (array: []) - List of headers to whitelist, allowing a plugin to include them in the response.

Additionally, the following options are allowed in Vault open-source, but relevant functionality is only supported in Vault Enterprise:

local (bool: false) – Specifies if the auth method is local only. Local auth methods are not replicated nor (if a secondary) removed by replication. Local auth mounts also generate entities for tokens issued. The entity will be replicated across clusters and the aliases generated on the local auth mount will be local to the cluster. If the goal of marking an auth method as local was to comply with GDPR guidelines, then care must be taken to not set the data pertaining to local auth mount or local auth mount aliases in the metadata of the associated entity. Metadata related to local auth mount aliases can be stored as custom_metadata on the alias itself which will also be retained locally to the cluster.
Warning: Remember, policies when using replication secondaries are validated by the local cluster. An administrator that can set up a local auth method mount can assign policies to tokens that are valid on the replication primary if a request is forwarded. Never give untrusted administrators the ability to assign policies or configure authentication methods.
seal_wrap (bool: false) - Enable seal wrapping for the mount, causing values stored by the mount to be wrapped by the seal's encryption capability.

Sample Payload

{
  "type": "github",
  "description": "Login with GitHub"
}

Sample Request

$ curl \
    --header "X-Vault-Token: ..." \
    --request POST \
    --data @payload.json \
    http://127.0.0.1:8200/v1/sys/auth/my-auth

Disable Auth Method

This endpoint disables the auth method at the given auth path.

sudo required – This endpoint requires sudo capability in addition to any path-specific capabilities.

Method	Path
`DELETE`	`/sys/auth/:path`

Parameters

path (string: <required>) – Specifies the path to disable. This is part of the request URL.

Sample Request

$ curl \
    --header "X-Vault-Token: ..." \
    --request DELETE \
    http://127.0.0.1:8200/v1/sys/auth/my-auth

Read Auth Method Tuning

This endpoint reads the given auth path's configuration. This endpoint requires sudo capability on the final path, but the same functionality can be achieved without sudo via sys/mounts/auth/[auth-path]/tune.

sudo required – This endpoint requires sudo capability in addition to any path-specific capabilities.

Method	Path
`GET`	`/sys/auth/:path/tune`

Parameters

path (string: <required>) – Specifies the path in which to tune.

Sample Request

$ curl \
    --header "X-Vault-Token: ..." \
    http://127.0.0.1:8200/v1/sys/auth/my-auth/tune

Sample Response

{
  "default_lease_ttl": 2764800,
  "description": "",
  "force_no_cache": false,
  "max_lease_ttl": 2764800,
  "token_type": "default-service"
}

Tune Auth Method

Tune configuration parameters for a given auth path. This endpoint requires sudo capability on the final path, but the same functionality can be achieved without sudo via sys/mounts/auth/[auth-path]/tune.

sudo required – This endpoint requires sudo capability in addition to any path-specific capabilities.

Method	Path
`POST`	`/sys/auth/:path/tune`

Parameters

default_lease_ttl (int: 0) – Specifies the default time-to-live. If set on a specific auth path, this overrides the global default.
max_lease_ttl (int: 0) – Specifies the maximum time-to-live. If set on a specific auth path, this overrides the global default.
description (string: "") – Specifies the description of the mount. This overrides the current stored value, if any.
audit_non_hmac_request_keys (array: []) - Specifies the list of keys that will not be HMAC'd by audit devices in the request data object.
audit_non_hmac_response_keys (array: []) - Specifies the list of keys that will not be HMAC'd by audit devices in the response data object.
listing_visibility (string: "") - Specifies whether to show this mount in the UI-specific listing endpoint. Valid values are "unauth" or "".
passthrough_request_headers (array: []) - List of headers to whitelist and pass from the request to the plugin.
allowed_response_headers (array: []) - List of headers to whitelist, allowing a plugin to include them in the response.
token_type (string: "") – Specifies the type of tokens that should be returned by the mount. The following values are available:
- default-service: Unless the auth method requests a different type, issue service tokens
- default-batch: Unless the auth method requests a different type, issue batch tokens
- service: Override any auth method preference and always issue service tokens from this mount
- batch: Override any auth method preference and always issue batch tokens from this mount
