I am using Keycloak to authenticate a user for a Vaadin application. The Vaadin application creates its own user session after successful authentication with Keycloak. I need the user to be able to change the password and email address.
Now I do not quite understand how to implement it correctly. There is a user Keycloak console that has this kind of functionality. But, for example, when a user changes their email address, the user is not prompted to confirm that new email address until a new login. Should I disable the Keycloak user console and e.g. use the Keycloak REST API directly from the Vaadin app to perform email/password changes? Or should I keep using Keycloak's custom console and configure it there?
What is the proper way to deal with such things with Keycloak? In case of Keycloak API I'd really appreciate the examples of API calls which should I perform in order to change the user password and email.

We have our own CRM portals and we want to offer OpenID based User authentication and authorization.
To achieve this we have decided to use Keycloak.
The flow we formalized is below and we are stuck due to may be not knowing much of the configurations inside Keycloak or may be its not possible.
User visits our existing CRM login page where he/she provides the username and password.
On click of Login the keycloak custom Identity provider should authenticate the user
Keycloak should receive the authentication success response and generate the JWT token
User is redirected back to CRM dashboard with the help of redirect_url configured in custom IDP.
What we have done till now,
Created a custom IDP inside Keycloak.
Configured all endpoints in this custom IDP
No custom authentication flow yet, all defaults i.e. First login flow is set to 'first broker login'
Challenges we are facing currently,
User on our CRM login page (Not the keycloak login form) and click on login button
The Keycloak login form is shown to user. We dont want any keycloak login pages. but instead the custom IDP endpoints should be executed and a JWT is returned back to redirected CRM application.
Is this possible to achieve the flow I mentioned above?
You need to adapt the browser Authentication Flow
Authentication -> Flows -> Browser
There you find the Identity Provider Redirector. Click Configure and specify a Default Identity Provider (you need the alias of your IDP there)
Normally all available IdentityProviders are listed beside the login form. But if a DefaultIdentityProvider is configured, KC immediately redirects to the external IDP.
We are using keycloak as auth provider by utilizing the OAuth Code Flow. The user logs in with their normal email and password on the keycloak login page. Is there a way to mask/hide or even map email adresses? Apple is doing this by saving the real email but using fake mails like j24hj21h4#apple.com for the "outer world". The reason I need this feature is to hide the real email adresses of our users for SSO.
From my point of view, your best bet would be extend the Authentication SPI of keycloak and implement your logic, it's is totally achievable.
This is not something you get out of keycloak by default, but it provides flexibility to plug our extensions.
Here you can find more details on this https://www.keycloak.org/docs/latest/server_development/#_auth_spi
I need to implement a login flow with KeyCloak where a user will be prompted to reauthenticate with an existing account (by email/password or via social IdP) after authentication with a non-existing social account OR choose to create a new KeyCloak account.
Something like on the picture below:
Is it possible to implement such a flow with KeyCloak?
It is possible that flow with regular Identity Providers feature in Keycloak
Overview Steps
detail information here
1. IDP URL
{keyclaok URL}/realms/{realm}/broker/{idp name}/endpoint
example:
http://localhost:8180/auth/realms/test/broker/stackoverflow/endpoint
2. Register Application at Social App
example: StackOverflow https://stackapps.com/
3. Get Client Information from Social App
example: StackOverflow
4. Set IDP at Keycloak
5. Test
5.1 Before add user
5.2 login by Social
5.3 Update user account (set password and e-mail)
5.4 check added user
5.5 Test added user login by username/password OR
Social Icon Click without credential
5.6 logged in test by both ways
5.7 Picked up e-mail from Facebook and detect e-mail already exists.
5.8 I select "Add to existing account" then filled out e-mail and password from Keycloak.
The authentication flows within Keycloak can be customized (virtually all of the flows can be customized or extended). I believe you'll need to implement a custom Authentication SPI (Service Provider Interface). This will be a JAR that you can add custom logic upon account creation.
Here's the Keycloak documentation for SPIs.
The realm in keycloak is configured with multiple IDPs like Azure, Okta, Google etc.
But username and password is something that is not needed.
In the browser Authentication flow if I disable Forms instead of "Alternative" the login page appears with "Invalid Username or Password"
Please note I want multiple IDPs buttons to appear in the login page without the Username and Password Login Form.
Not much is documented about this in keycloak documentation.
You can use a custom authentication provider to achieve your goal.
Instruct Keycloak to assign a specific user attribute to all users arriving from the IDP.
Build an authentication provider which checks for that user attribute and denies access.
Add the authentication provider to the Browser login flow.
Create new theme and adjust templates files to hide login fields and show a user-friendly error if the user fails step 2. Use theme only on relevant realm.

How to disable username/password login for external IDP ?
I know that I can use custom theme to hide http form, but I want to do it properly.
As far as I know I have to create at least custom First Broker Login and Browser authentication flow, right?
After first login from IDP I have to create user in Keycloak, but do not leverage password option.
Also Browser flow must be updated to not show username/password form, right?
Can anyone provide proper example ?
Thanks

May not be 100% suitable to this case, but found next one working fine for our case without need to compile and deploy "custom authentication provider". In our app we suppress keycloak login form and offer own custom user / password form, and for IdP integration we are using kc_hint to redirect directly to IdP login page. Once user login via IdP we want to disable user name / password login using password grant. There is a trick allows to achieve this in keycloak v15. You can assign "Update User Locale" to "Required User Actions" of the user, from that moments, direct password grant wont let user to login returning "requires action" validation error, which is not supported in our UI, while IdP login still works and skip this "required action" nor reset it after login. Of course you may need some scheduled curl script allows to set this for users automatically via users REST API : read users attributes or IdP link integration, if found specific Idp related user attribute or IdP integration link, and "requires action" array is empty, set it to "Update Locale".
Of course this all works as long as you hide keycloak login form and use your own. for all using keycloak login form, login using name / password will work and can bypass "Update locale" requirement (not sure why, perhaps because realm does not have locales configured)
Try this costum Authentication flow
By Automatically linking brokered account, the user won't have to set a password. as for the username it will be automatically imported from the identity provider.
