Configure JWT authentication

You can configure Grafana to accept a JWT token provided in the HTTP header. The token is verified using any of the following:

  • PEM-encoded key file
  • JSON Web Key Set (JWKS) in a local file
  • JWKS provided by the configured JWKS endpoint

This method of authentication is useful for integrating with other systems that use JWKS but can’t directly integrate with Grafana or if you want to use pass-through authentication in an app embedding Grafana.

Enable JWT

To use JWT authentication:

  1. Enable JWT in the main config file.
  2. Specify the header name that contains a token.
# By default, auth.jwt is disabled.
enabled = true

# HTTP header to look into to get a JWT token.
header_name = X-JWT-Assertion

Configure login claim

To identify the user, some of the claims needs to be selected as a login info. The subject claim called "sub" is mandatory and needs to identify the principal that is the subject of the JWT.

Typically, the subject claim called "sub" would be used as a login but it might also be set to some application specific claim.

# [auth.jwt]
# ...

# Specify a claim to use as a username to sign in.
username_claim = sub

# Specify a claim to use as an email to sign in.
email_claim = sub

# auto-create users if they are not already matched
# auto_sign_up = true

If auto_sign_up is enabled, then the sub claim is used as the “external Auth ID”. The name claim is used as the user’s full name if it is present.

Iframe Embedding

If you want to embed Grafana in an iframe while maintaining user identity and role checks, you can use JWT authentication to authenticate the iframe.


For Grafana Cloud, or scenarios where verifying viewer identity is not required, embed public dashboards.

In this scenario, you will need to configure Grafana to accept a JWT provided in the HTTP header and a reverse proxy should rewrite requests to the Grafana instance to include the JWT in the request’s headers.


For embedding to work, you must enable allow_embedding in the security section. This setting is not available in Grafana Cloud.

In a scenario where it is not possible to rewrite the request headers you can use URL login instead.

URL login

url_login allows grafana to search for a JWT in the URL query parameter auth_token and use it as the authentication token.

Note: You need to have enabled JWT before setting this setting see section Enabled JWT


this can lead to JWTs being exposed in logs and possible session hijacking if the server is not using HTTP over TLS.
# [auth.jwt]
# ...
url_login = true # enable JWT authentication in the URL

An example of an URL for accessing grafana with JWT URL authentication is:


A sample repository using this authentication method is available at grafana-iframe-oauth-sample.

Signature verification

JSON web token integrity needs to be verified so cryptographic signature is used for this purpose. So we expect that every token must be signed with some known cryptographic key.

You have a variety of options on how to specify where the keys are located.

Verify token using a JSON Web Key Set loaded from https endpoint

For more information on JWKS endpoints, refer to Auth0 docs.

# [auth.jwt]
# ...

jwk_set_url =

# Cache TTL for data loaded from http endpoint.
cache_ttl = 60m

Note: If the JWKS endpoint includes cache control headers and the value is less than the configured cache_ttl, then the cache control header value is used instead. If the cache_ttl is not set, no caching is performed. no-store and no-cache cache control headers are ignored.

Verify token using a JSON Web Key Set loaded from JSON file

Key set in the same format as in JWKS endpoint but located on disk.

jwk_set_file = /path/to/jwks.json

Verify token using a single key loaded from PEM-encoded file

PEM-encoded key file in PKIX, PKCS #1, PKCS #8 or SEC 1 format.

key_file = /path/to/key.pem

If the JWT token’s header specifies a kid (Key ID), then the Key ID must be set using the key_id configuration option.

key_id = my-key-id

Validate claims

By default, only "exp", "nbf" and "iat" claims are validated.

You might also want to validate that other claims are really what you expect them to be.

# This can be seen as a required "subset" of a JWT Claims Set.
expect_claims = {"iss": "https://your-token-issuer", "your-custom-claim": "foo"}


Grafana checks for the presence of a role using the JMESPath specified via the role_attribute_path configuration option. The JMESPath is applied to JWT token claims. The result after evaluation of the role_attribute_path JMESPath expression should be a valid Grafana role, for example, Viewer, Editor or Admin.

The organization that the role is assigned to can be configured using the X-Grafana-Org-Id header.

JMESPath examples

To ease configuration of a proper JMESPath expression, you can test/evaluate expressions with custom payloads at

Role mapping

If the role_attribute_path property does not return a role, then the user is assigned the Viewer role by default. You can disable the role assignment by setting role_attribute_strict = true. It denies user access if no role or an invalid role is returned.

Basic example:

In the following example user will get Editor as role when authenticating. The value of the property role will be the resulting role if the role is a proper Grafana role, i.e. Viewer, Editor or Admin.


    "role": "Editor",


role_attribute_path = role

Advanced example:

In the following example user will get Admin as role when authenticating since it has a role admin. If a user has a role editor it will get Editor as role, otherwise Viewer.


    "info": {
        "roles": [


role_attribute_path = contains(info.roles[*], 'admin') && 'Admin' || contains(info.roles[*], 'editor') && 'Editor' || 'Viewer'

Grafana Admin Role

If the role_attribute_path property returns a GrafanaAdmin role, Grafana Admin is not assigned by default, instead the Admin role is assigned. To allow Grafana Admin role to be assigned set allow_assign_grafana_admin = true.

Skip organization role mapping

To skip the assignment of roles and permissions upon login via JWT and handle them via other mechanisms like the user interface, we can skip the organization role synchronization with the following configuration.

# ...

skip_org_role_sync = true
