In this tutorial, learn how to configure JSON Web Tokens (JWT) and how to use Qlik Associative Engine to manage and authenticate users.

JSON Web Token

JWT is an open standard for creating access tokens. To learn more about JWT, see the JWT documentation and the JWT Standard.

The Qlik Associative Engine uses JWTs for the following tasks:

  • Ensuring that only authenticated users are allowed to connect.
  • Connecting users to the same sessions.
  • Applying data security (for example, section access).
  • Enforcing document level access control.

JWT format

A typical JWT consists of three parts.



Each part of the JWT is base64url-encoded and separated by a dot. To learn more about JWT encoding, see Base 64 Encoding with URL and Filename Safe Alphabet.

The header describes the type of token, and the hashing algorithm that is used to sign the token. For example:

  "typ": "JWT",
  "alg": "none"


The payload contains the claims of the JWT. The relevant claims that are evaluated by the Qlik Associative Engine are the subject and the expiration date.

Field Mandatory Description
sub Yes The subject is a unique identifier for a user. 
exp No The numerical expiration date. If omitted it never expires.
groups No Array of user groups. If present the GROUP column can be used in section access
kid No Reserved field for JWKS in the future.

For example:

  "sub": "jdoe",
  "exp": "1541173994"


The signature is used to verify the authenticity of the token. The Qlik Associative Engine supports the following JWT signing algorithms:

Encryption type Algorithms
HMAC HS256, HS384, HS512
Elliptic curve ES256, ES384, ES512
RSA RS256, RS384, RS512

To learn more about JWT signatures, see Signature.

Qlik Associative Engine configuration

To validate JWTs, you must configure the Qlik Associative Engine by specifying the JWT enforcement type and the JWT secret in the docker-compose.yml file.

The enforcement type is defined as:

-S ValidateJsonWebTokens=<enforcement type>

where enforcement type is one of the following values:

Value Description
0 Not enforced (default)
1 Enforce JWT validation (JWT can be either signed or unsigned)
2 Enforce JWT validation (JWT must be signed)

HMAC secrets are injected through the command line parameter:

-S JsonWebTokenSecret=<secret>

Elliptic curve and RSA secrets are retrieved from a public key, stored on a pem file.

-S JsonWebTokenPath=<path to pem file>


version: "3.1"

    image: qlikcore/engine
    command: -S ValidateJsonWebTokens=2 -S JsonWebTokenSecret=passw0rd


The JWT is passed to the Qlik Associative Engine in the Authorization header using the Bearer schema, and is validated once the websocket connection is established.

Authorization: Bearer <token>

In order for validation to be successful, two conditions must be met:

  1. The signature must be valid.
  2. If the exp field exists, then the expiry date must not have passed.

If validation fails, the request is rejected and a 401 Unauthorized HTTP response code is returned.

Section access

You can use section access to segment application data so specific sections are available only to certain users or groups. To learn more about section access, see Managing security with section access.


Qlik Associative Engine has to be started with -S ValidateJsonWebTokens=< 1 or 2 > otherwise the error Section access detected when opening an app in QlikView Personal. will be shown.

Managing access control

Access control is managed through one or several security tables loaded in the same way that the Qlik Associative Engine normally loads data.

In the example below, the load script grants regional users access to their respective country data while the admin user has access to all data.

section access;
LOAD * inline [
ADMIN, admin,,
USER, us-user,US,
USER, uk-user,UK,
USER, de-user,DE,

section Application;
US, Electronics, 101
US, Furniture, 102
US, Other, 103
UK, Electronics, 201
UK, Furniture, 202
UK, Other, 203
DE, Electronics, 301
DE, Furniture, 302
DE, Other, 303

The Qlik Associative Engine maps the sub field from the JWT to the user names that are specified in the section access table. In the example above, the section access table is linked to the Sales table through the COUNTRY field value, which allows the visibility of row data to be controlled by section access.

If the JWT contains the groups field it will be mapped to the 'GROUP' column in the section access table.
