How to Implement Email Verification in Keycloak
Keycloak simplifies the process of implementing email verification with its user-friendly interface and robust features. Here's a step-by-step guide:
1. Set Up a Keycloak Realm
If you haven't already, create a Keycloak realm for your application. Realms isolate a set of applications and users from others.
2. Configure User Registration
Within your realm, configure user registration to require email verification. Go to "Realm Settings" -> "Login" -> "User Registration" and set "Verify email" to "On."
3. Customize Email Templates
Keycloak provides email templates for various actions, including email verification. You can customize these templates to match your application's branding and messaging.
4. Registration Flow
In "Realm Settings" -> "Login" -> "Registration" tab, configure the registration flow. Ensure that "Registration Email" is included in the list of execution steps. This step sends an email for verification.
5. User Experience
With the setup complete, users will now be required to verify their email addresses during registration. Keycloak will send an email containing a verification link to the provided email address.
6. User Authentication
Once users click the verification link, their email addresses are confirmed, and they can log in securely.
Customization Options for Email Verification
Keycloak offers customization options to tailor the email verification process to your application's needs:
1. Email Templates
Customize email templates to match your application's branding and provide clear instructions for users.
