🔑Keycloak Configuration Guide

Let's spin up a Keycloak server and configure it for your webapp!

Provisioning a Keycloak server

If you already have access to a Keycloak server you can skip this section.

Managed Keycloak instance

Don't want to deploy and maintain a own Keycloak server yourself?

Choosing Keycloak as a Service through a cloud IAM provider can offload the complexities of management and maintenance. It ensures that your system is always up-to-date with the latest security patches and features without the direct overhead of server upkeep. This is especially beneficial for teams prioritizing development and innovation over infrastructure management, offering robust support and service level agreements to guarantee smooth operation.

Configuring your Keycloak server

Let's configure your Keycloak server with good default for an SPA.

Connect to the admin panel of your Keycloak server (we assumes it's https://auth.my-domain.net/auth)

• Create a realm called "myrealm" (or something else), go to Realm settings

  1. On the tab General

     1. User Profile Enabled: On

  2. On the tab login

     1. User registration: On

     2. Forgot password: On

     3. Remember me: On

  3. On the tab email, we give an example with AWS SES, if you don't have a SMTP server at hand you can skip this by going to Authentication (on the left panel) -> Tab Required Actions -> Uncheck "set as default action" Verify Email. Be aware that with email verification disable, anyone will be able to sign up to your service.

     1. From: [e-mail]

     2. Host: email-smtp.us-east-2.amazonaws.com

     3. Port: 465

     4. Authentication: enabled

     5. Username: **************

     6. Password: ***************************************

     7. When clicking "save" you'll be asked for a test email, you have to provide one that correspond to a pre-existing user or you will get a silent error and the credentials won't be saved.

  4. On the tab Themes. See Keycloakify for creating a Keycloak theme that match your webapp.
  5. On the tab Localization

     1. Internationalization: Enabled

     2. Supported locales: <Select the languages you wish to support>

  6. On the tab Sessions

     1. SSO Session Idle: 14 days - This is where you configure the auto logout policy. If you want your user to be automatically loged out after 30 minutes, set it here.

     2. SSO Session Max: 14 days

     3. SSO Session Idle Remember Me: 365 days - Same than SSO Session Idle but when the user have checked "Remember me" when login in. If you have enaled "remeber me" and you want this option to make sens you must set it to a value that is greater than SSO Session Idle. If you have set SSO Session Idle to something short because you want to implement an auto logout policy you probably want to go in Realm -> login and disable "Remember me"

     4. SSO Session Max Remember Me: 365 days - Same note here.

• Create a new OpenID Connect client called "myclient" (or something else) by accessing Clients -> Create Client

  1. Root URL: https://your-domain.net (or something else, your app does not need to be on the

  the same domain as your Keycloak).

  1. Valid redirect URIs: https://onyxia.my-domain.net/*, http://localhost* (for testing in local)

  2. Web origins: *

  3. Login theme: keycloak (or your theme if you have one)

• (OPTIONAL) In Authentication (on the left panel) -> Tab Required Actions enable and set as default action Therms and Conditions. (You can use Keycloakify to specify your therme and condition, see next section)

• (OPTIONAL) On the left pannel you can go to identity provider to enable login via Google, GitHub, Instagram, ect...

• (OPTIONAL) Enable your user to delete their own account (see user account managment)

  1. In the left bar navigate to Autentication -> Required Action -> "Delete Account" Enabled: On

  2. In the left bar navigate to Realm Setting -> User Registration -> Default Roles -> Assign Role -> Filter by client -> select Delete Account and click on assign.

Now the parameter that you will have to provide to oidc-spa are:

    issuerUri: "https://auth.your-domain.net/realms/myrealm",
    clientId: "myclient"

Replace your-domain.net, myrealm and myclient by what you actually used in the configuration process. (On older Keycloak the issuerUri will be "https://auth.your-domain.net/auth/realms/myrealm")
