In older versions of keycloak, the Access-Type of a client can be set in Settingļ½ tab as follows
But in keycloak version 20.0.1, there is no Access type field in the client Settings tab as follows:
Where can I set Access-Type of the client with keycloak 20.0.1?
As one can read on the following groups.google.com keycloak threads:

The new admin console designs are dropping the "bearer-only" option for a
client:
https://marvelapp.com/prototype/908c3c3/screen/72041413
This makes perfectly sense to me, as a "bearer-only" client is really
only a client that doesn't leverage any of the OAuth flows.
The option of explicitly setting the access-type of clients to bearer-only is not longer available on the new Keycloak Admin Console UI. Nonetheless, with the new UI one can still see clients that were previously (in older versions) created with access-type bearer-only. However, one cannot change their access-type.
Even though the new UI does not have the option to explicitly set the access-type to bearer-only, one can still create an equivalent bearer-only client by unchecking all the Authentications flows, as follows:

I have installed several application on a BizTalk 2020 server using BTDF 5.8 where I used to the application settings in the deployment to update any config for the BizTalk applications.
My own account is part of the SSO admin group and I use the in proc host account to install the apps into the BizTalk server. The proc host account is also part of the SSO admin group.
When I view the SSO using the admin or client utility no apps are shown. I also downloaded and run the BizTalk-Server-SSO-Application-Configuration-Tool. The tool also showed no current installed applications, but was able to add an application with it config.
But ideally I would like to view and edit current config as I am currently getting an error on a server with incorrect value.
Is there another tool to view and edit settings or am I missing something that must be enabled.
I'm creating Java appliation, where I will need users to log in. Currently I'm verifying if I can configure Keycloak safe enough. I'd like to make sure my application is really authenticating users against my Keycloak server - eg I know there is something like DNS Poisining or other attacks, where my application could get to attackers server with duplicated/attackers Keycloak instance. What surprised me, I have currently configuration with follwing keys:
keycloak.auth-server-url=...
keycloak.realm=...
keycloak.resource=...
keycloak.public-client=true
keycloak.security-constraints[0].authRoles[0]=..
keycloak.security-constraints[0].securityCollections[0].patterns[0]=...
keycloak.principal-attribute=preferred_username
and no public key is needed. Even worse here: https://stackoverflow.com/a/40516696/520521 I see upvoted comment telling, my application may download key from (malicious) server.
Are there any extra steps I need to follow, to authenticate Keycloak server before starting to authenticate users against it?
Based on your configuration, it seems that you've defined your client in Keycloak as public. This allows your client to be able to call Keycloak without any authentication. This type of client is used for example when you're going to authenticate via js in webpage in which nothing can be hidden from attacker as they have access to the source of the page.
If you set the "Access Type" of your client to "confidential" (in Client Settings on Keycloak Admin UI) and save the settings, there will appear another tab (next to "Setting" tab of the client) titled "Credentials". There you can see the default secret that is created for your client. You should then put this secret as below in your keycloak.json file inside your application:
"credentials": {
"secret": "paste-the-secret-value-here"
}
You can also re-generate the value by selecting the "Regenerate Secret" button.
You can also change the "Client Authenticator" there and set it to "X509 Certificate". Then you would be asked to define a regular expression to validate the "Subject DN" of the certificate that client will be using for authentication. Any certificate matching that regex would be considered as valid and authenticated. Then you have to setup your client to use such certificate instead of defining the "secret" value in the keycloak.json file.
There is of course another option which uses "Signed JWT" which is also secure and you can find the details about how to set it up in Keycloak documentation at Client Authentication section.
I can't see a word that this is the aim, but seeing where public and private key is placed I understand that answer is, that in realm settings -> keys -> active there is list of keys. You may download public key or certificate with button on right side. In my case of Spring boot, enter application.properties file a public key under keycloak.realm-key.
I have a query about how keycloak is supposed to be working with client without GUI access.
Basically I have:
A keycloak server configured with a realm, clients(Access type confidential) and Users
A server application with a GUI that also provide API, secure with keycloak (client, user, blablabla)
This is kind of working already as I am able to log on the GUI, have the redirect, etc..
Even accessing the APIs works well, when I have access to a GUI: I log on my UI, follow the redirect and get my UI to display the token. The the human (to differentiate the user from an application), can use the token in any API client.
In this context the user never sees the client secret, which is instinctively the right way. (note that I am very opened to people telling me my instinct is wrong!)
What I am NOT able to do so far is to find the way a server application (without GUI) can get a valid token?
The authorization_endpoint, as far as I understand it, requires both the client id and the client secret) to get a token, which I would rather avoid: I don't think giving my client secret to all my "customers" is the proper way to do it.
Alternatively I could create an API on my client that woudl ask for user credential and ask for the token in its behalf, but that would expose the clients credentials to my application, which is against the whole concept!
I tried setting my client Access type as public, but when I use the API call below I also get a error:
POST /auth/realms/realmname/protocol/openid-connect/tokenAPI
'grant_type=client_credentials'
'client_id=client_id'
'username=username'
'password=password'
{
"error": "unauthorized_client",
"error_description": "Public client not allowed to retrieve service account"
}
Would anyone know how this is supposed to be done ?
Thanks in advance.

(...) A server application (without GUI) can get a valid token... typically using the Client Credentials flow.
But we would define in this case a dedicated Client for your server (client?) application to authenticate against. The returned token (not bound to a specific user) will serve for authorizations on allowed applications (i.e. your classic GUI or API clients).
So, basically you should (in very short):
define a specific confidential Client in your Keycloak
add the desired applications (or other Clients) to the Client Scope(s). Those you want to authorize transitively from this Client.
authenticate against this Client with Client Credentials flow (given the token endpoint, client id, credentials, scope)
ensure that you are authenticating through TLS and that parameters are included in request body (and not in headers - for enhanced privacy)
further harden security of your Client(s)
When you do not want anymore this particular server (client?) application to access your applications, you can change the corresponding "authentication" Client's secret/credentials or simply delete it.
"I don't think giving my client secret to all my "customers" is the proper way to do it."
You are right and the proposed method above strictly avoids that. Each customer would have its own credentials.
EDIT
(adding more details)
By performing as above, you would end up with the following scheme:
Flow Keycloak Server
C/S app. or Customer X <--- Client Creds ---> Auth. Client X
--- Access Token ---> Appl. Client <--> Appl. Server
C/S app. or Customer Y <--- Client Creds ---> Auth. Client Y
--- Access Token ---> Appl. Client <--> Appl. Server
Browser users <--- Standard ------> Appl. Client <--> Appl. Server
Note: this is not a detailed flow chart. Arrows mostly show relationships here.
Finally, please note that the terminology may differ a little here, but the proposed method is basically the same that Google uses. So you may aswell take some inpiration from there:

I just had the same problem some weeks ago
In my case, I have a backend API and a frontend application that the users can use.
Eventually, I can't share the client_secret to the frontend application.
So here is my solution:
On keycloak, create a client (ex front_end_client) with grant type public
This client is going to be used by the frontend application to authenticate users using implicit flow (with PKCE will be more secure)
On keycloak, create a second client (On the same REALM as the first client) with grant type confidential, this client is going to be used by the backend API
Now, this is how it works:
Frontend app authenticate users and get the access token (Using the font_end_client)
The frontend app sends this token for every request to the backend
Backend app verify this token, and can retrieve permissions from it
Hi i am a bit confused as to how to secure applications through keycloak, the website shows how to secure clients. The application which i need to secure in my setup is a desktop application which uses keycloak + keycloak-gatekeeper protected endpoints.
i managed to get it working using the following library in python
https://bitbucket.org/agriness/python-keycloak/src/master/
however, it requires me to enter the client-secret and i am wondering if this is safe?
also, when i use the browser login instead, the browser doesnt need the client secret, but goes though gatekeeper, this tells me that i am doing something wrong here.
thanks
Use public access type client (Clients doc):
Public access type is for client-side clients that need to perform a browser login. With a client-side application there is no way to keep a secret safe. Instead it is very important to restrict access by configuring correct redirect URIs for the client.
You can change access type on clients - choose client - settings tab admin interface.
in your case, I would use Access type as confidential
and Authorization Enabled > on
and you should use the secrecy key to authorize your call to keylock when you want to interact with keycloak API
Keycloak keycloak = KeycloakBuilder.builder()
.serverUrl("localhost")
.realm("myRealm")
.grantType(OAuth2Constants.PASSWORD)
.clientId("myclient")
.clientSecret("xxxx-xxxxx-xxxx-xxx")
.username("foo")//the admin user
.password("password")
.build();
keycloak.realm("myRealm").users().list();
We are considering to use the keycloak as our SSO framework.
According to the keycloak documentation for multi-tenancy support the application server should hold all the keycloak.json authentication files, the way to acquire those files is from the keycloak admin, is there a way to get them dynamically via API ? or at least to get the realm public key ? we would like to avoid to manually add this file for each realm to the application server (to avoid downtime, etc).
Another multi-tenancy related question - according to the documentation the same clients should be created for each realm, so if I have 100 realms and 10 clients, I should define the same 10 clients 100 times ? is there an alternative ?
One of our flows is backend micro-service that should be authenticated against an application (defined as keycloak client), we would like to avoid keeping user/psw on the server for security reasons, is there a way that an admin can acquire a token and place it manually on the server file system for that micro service ? is there a option to generate this token in the keycloak UI ?
Thanks in advance.
All Keycloak functionality is available via the admin REST API, so you can automate this. The realm's public key is available via http://localhost:8080/auth/realms/{realm}/
A realm for each tenant will give a tenant-specific login page. Therefore this is the way to go - 10 clients registered 100 times. See more in the chapter Client Registration of the Keycloak documentation. If you don't need specific themes, you can opt to put everything in one realm, but you will lose a lot of flexibility on that path.
If your backend micro service should appear like one (technical) user, you can issue an offline token that doesn't expire. This is the online documentation for offline tokens. Currently there is no admin functionality to retrieve an offline token for a user by an admin. You'll need to build this yourself. An admin can later revoke offline tokens using the given admin API.
