# JWT/OIDC Auth Method (API)

This is the API documentation for the Vault JWT/OIDC auth method
plugin. To learn more about the usage and operation, see the
[Vault JWT/OIDC method documentation](/docs/auth/jwt).

This documentation assumes the plugin method is mounted at the
`/auth/jwt` path in Vault. Since it is possible to enable auth methods
at any location, please update your API calls accordingly.

## Configure

Configures the validation information to be used globally across all roles. One
(and only one) of `oidc_discovery_url`, `jwks_url`, and `jwt_validation_pubkeys` must be
set.

| Method | Path               |
| :----- | :----------------- |
| `POST` | `/auth/jwt/config` |

### Parameters

- `oidc_discovery_url` `(string: <optional>)` - The OIDC Discovery URL, without any .well-known component (base path). Cannot be used with "jwks_url" or "jwt_validation_pubkeys".
- `oidc_discovery_ca_pem` `(string: <optional>)` - The CA certificate or chain of certificates, in PEM format, to use to validate connections to the OIDC Discovery URL. If not set, system certificates are used.
- `oidc_client_id` `(string: <optional>)` - The OAuth Client ID from the provider for OIDC roles.
- `oidc_client_secret` `(string: <optional>)` - The OAuth Client Secret from the provider for OIDC roles.
- `oidc_response_mode` `(string: <optional>)` - The response mode to be used in the OAuth2 request. Allowed values are "query" and "form_post". Defaults to "query". If using Vault namespaces, and oidc_response_mode is "form_post", then "namespace_in_state" should be set to false.
- `oidc_response_types` `(comma-separated string, or array of strings: <optional>)` - The response types to request. Allowed values are "code" and "id_token". Defaults to "code".
  Note: "id_token" may only be used if "oidc_response_mode" is set to "form_post".
- `jwks_url` `(string: <optional>)` - JWKS URL to use to authenticate signatures. Cannot be used with "oidc_discovery_url" or "jwt_validation_pubkeys".
- `jwks_ca_pem` `(string: <optional>)` - The CA certificate or chain of certificates, in PEM format, to use to validate connections to the JWKS URL. If not set, system certificates are used.
- `jwt_validation_pubkeys` `(comma-separated string, or array of strings: <optional>)` - A list of PEM-encoded public keys to use to authenticate signatures locally. Cannot be used with "jwks_url" or "oidc_discovery_url".
- `bound_issuer` `(string: <optional>)` - The value against which to match the `iss` claim in a JWT.
- `jwt_supported_algs` `(comma-separated string, or array of strings: <optional>)` - A list of supported signing algorithms. Defaults to [RS256] for OIDC roles. Defaults to all [available algorithms](https://github.com/hashicorp/vault-plugin-auth-jwt/blob/master/vendor/github.com/hashicorp/cap/jwt/algs.go#L12-L21) for JWT roles.
- `default_role` `(string: <optional>)` - The default role to use if none is provided during login.
- `provider_config` `(map: <optional>)` - Configuration options for provider-specific handling. Providers with specific handling include: Azure, Google. The options are described in each provider's section in [OIDC Provider Setup](/docs/auth/jwt_oidc_providers).
- `namespace_in_state` `(bool: true)` - Pass namespace in the OIDC state parameter instead of as a separate query parameter. With this setting, the allowed redirect URL(s) in Vault and on the provider side should not contain a namespace query parameter. This means only one redirect URL entry needs to be maintained on the provider side for all vault namespaces that will be authenticating against it. Defaults to true for new configs.

### Sample Payload

## Create Role

Registers a role in the method. Role types have specific entities
that can perform login operations against this endpoint. Constraints specific
to the role type must be set on the role. These are applied to the authenticated
entities attempting to login. At least one of the bound values must be set.

| Method | Path                   |
| :----- | :--------------------- |
| `POST` | `/auth/jwt/role/:name` |

### Parameters

- `name` `(string: <required>)` - Name of the role.
- `role_type` `(string: <optional>)` - Type of role, either "oidc" (default) or "jwt".

  Any match is sufficient. Required for "jwt" roles, optional for "oidc" roles.
- `user_claim` `(string: <required>)` - The claim to use to uniquely identify
  the user; this will be used as the name for the Identity entity alias created
  due to a successful login. The claim value must be a string.
- `clock_skew_leeway` `(int or string: <optional>)` - The amount of leeway to add to all claims to
  account for clock skew, in seconds. Defaults to `60` seconds if set to `0` and can be disabled
  if set to `-1`. Accepts an integer number of seconds, or a Go duration format string. Only applicable
  with "jwt" roles.
- `expiration_leeway` `(int or string: <optional>)` - The amount of leeway to add to expiration (`exp`) claims to
  account for clock skew, in seconds. Defaults to `150` seconds if set to `0` and can be disabled
  if set to `-1`. Accepts an integer number of seconds, or a Go duration format string. Only applicable
  with "jwt" roles.
- `not_before_leeway` `(int or string: <optional>)` - The amount of leeway to add to not before (`nbf`) claims to
  account for clock skew, in seconds. Defaults to `150` seconds if set to `0` and can be disabled
  if set to `-1`. Accepts an integer number of seconds, or a Go duration format string. Only applicable
  with "jwt" roles.
- `bound_subject` `(string: <optional>)` - If set, requires that the `sub`
  claim matches this value.
- `bound_claims` `(map: <optional>)` - If set, a map of claims (keys) to match against respective claim values (values).
  The expected value may be a single string or a list of strings. The interpretation of the bound
  claim values is configured with `bound_claims_type`. Keys support [JSON pointer](/docs/auth/jwt#claim-specifications-and-json-pointer)
  syntax for referencing claims.
- `bound_claims_type` `(string: "string")` - Configures the interpretation of the bound_claims values.
  If `"string"` (the default), the values will treated as string literals and must match exactly.
  If set to `"glob"`, the values will be interpreted as globs, with `*` matching any number of
  characters.
- `groups_claim` `(string: <optional>)` - The claim to use to uniquely identify
  the set of groups to which the user belongs; this will be used as the names
  for the Identity group aliases created due to a successful login. The claim
  value must be a list of strings. Supports [JSON pointer](/docs/auth/jwt#claim-specifications-and-json-pointer)
  syntax for referencing claims.
- `claim_mappings` `(map: <optional>)` - If set, a map of claims (keys) to be copied to
  specified metadata fields (values). Keys support [JSON pointer](/docs/auth/jwt#claim-specifications-and-json-pointer)
  syntax for referencing claims.
- `oidc_scopes` `(list: <optional>)` - If set, a list of OIDC scopes to be used with an OIDC role.
  The standard scope "openid" is automatically included and need not be specified.

  during OIDC logins.
- `verbose_oidc_logging` `(bool: false)` - Log received OIDC tokens and claims when debug-level
  logging is active. Not recommended in production since sensitive information may be present
  in OIDC responses.
- `max_age` `(int or string: <optional>)` - Specifies the allowable elapsed time in seconds since the last
  time the user was actively authenticated with the OIDC provider. If set, the `max_age` request parameter
  will be included in the authentication request. See [AuthRequest](https://openid.net/specs/openid-connect-core-1_0.html#AuthRequest)
  for additional details. Accepts an integer number of seconds, or a Go duration format string.
