Keycloack - get accessToken via Password grantType - requires client_secret

Question

As a newbie of Keycloak, I try to configure a client with a "Password" grant type. I know that this is not the preferred solution in most cases.

I created a realm 'realm2' with a client 'myclient2' and a user.

When trying to get the token with Postman, I get this error:

{
    "error": "unauthorized_client",
    "error_description": "Client secret not provided in request"
}

When I add the client_secret, I get the token. I tried to provide a username and password and no secret.

Via the Keycloak user interface I can also login as 'johan' in the 'realm2'.

This is my request in Postman:

In Keycloak I configured the 'realm2' with no special properties set:

The client 'myclient2' is:

I can see on the Credentials tab of the client:

I configured 1 user in the realm2 with just 'password' as a password:

How can I configure my Keycloack settings so I don't need the 'secret' but the username and password?

Answer 1

You could disable authentication for the client, making it public. You can do this by turning off "Client authentication" under the settings tab of your client.

EDIT: I just realized your keycloak version seems different to mine. This configuration is likely under the Access Type selector in your settings tab, by changing it from confidential to public
