Keycloak Self-Registration: A Step-by-Step Guide

1. Basic Setup

To get started with Keycloak self-registration, you need to have Keycloak installed. For this guide, we will assume you are using the default installation, which can be accessed through a web browser at http://localhost:8080/auth.

a. Access the Admin Console

Open your web browser and navigate to http://localhost:8080/auth/admin/. Log in with your admin credentials.

b. Create a Realm

A realm is the top-level container for all Keycloak data. Click on the "Realms" link in the sidebar and then click "Create Realm".

c. Configure Realm Settings

Enter a realm name, realm identifier, and realm display name. Choose a theme and click "Create".

d. Create a User Federation

To enable self-registration, you need to set up a user federation. Click on the "Federations" link in the sidebar and then click "Add federation".

Select "User federation" and click "Create". Configure the necessary settings, such as the realm to which the users will belong.

e. Enable Self-Service Registration

Navigate to the "Realm Settings" page and then to the "General Settings" tab. Scroll down to the "User federation" section and enable "Self-service registration".

2. Advanced Configuration

a. Customize Registration Attributes

Keycloak allows you to customize the attributes that users must provide during registration. Navigate to the "Realm Settings" page and then to the "General Settings" tab. Scroll down to the "User registration" section and click on the "Customize" link.

Here, you can add or remove attributes that users must provide. For example, you might require users to provide their email address or phone number.

b. Set up Account Confirmation

To ensure the authenticity of registered users, you can set up account confirmation. Navigate to the "Realm Settings" page and then to the "General Settings" tab. Scroll down to the "User registration" section and enable "Email confirmation".

Keycloak will send a confirmation email to the user's provided email address. The user must click the link in the email to activate their account.

c. Configure Email Templates

Keycloak allows you to customize the email templates sent to users during the registration process. Navigate to the "Realm Settings" page and then to the "Email templates" section.

Here, you can edit the templates for account confirmation, welcome emails, and other notifications.

b. Register a New User

Follow the registration steps provided by Keycloak. If everything is configured correctly, you should be able to create a new user account.
