WSO2 Guide for Email Validation

Using WSO2 IS to Implement Email Verification

Backend Script Using Java

import org.wso2.carbon.user.core.service.RealmService;
import org.wso2.carbon.user.core.UserStoreManager;
import org.wso2.carbon.user.api.UserStoreException;
import org.wso2.carbon.identity.mgt.services.UserIdentityManagementAdminService;
import org.wso2.carbon.identity.mgt.services.UserIdentityManagementAdminServiceImpl;
public class EmailValidator {
    private RealmService realmService;
    public EmailValidator(RealmService realmService) {
        this.realmService = realmService;
    }
    public boolean validateEmailExists(String email) throws UserStoreException {
        UserStoreManager userStoreManager = realmService.getTenantUserRealm(-1234).getUserStoreManager();
        return userStoreManager.isExistingUser(email);
    }
    public void sendResetLink(String email) {
        if (validateEmailExists(email)) {
            UserIdentityManagementAdminService adminService = new UserIdentityManagementAdminServiceImpl();
            adminService.forgetPassword(email);
        } else {
            System.out.println("Email does not exist in the system.");
        }
    }
}

JavaScript on the Front End for Email Validation

Client-side Script Using JavaScript

document.getElementById('reset-password-form').addEventListener('submit', function(event) {
    event.preventDefault();
    var email = document.getElementById('email').value;
    fetch('/api/validate-email', {
        method: 'POST',
        headers: {
            'Content-Type': 'application/json'
        },
        body: JSON.stringify({ email: email })
    }).then(response => response.json())
      .then(data => {
        if (data.exists) {
            alert('Reset link sent to your email.');
        } else {
            alert('Email does not exist.');
        }
    });
});

FAQs for Email Validation in WSO2 IS

1. In what way can I set up WSO2 IS to verify email formats?
2. Using regex patterns in the user store configurations or identity management feature scripting, you can modify the email validation process.
3. What are the advantages of limiting WSO2 IS password reset mailings to a corporate domain?
4. By guaranteeing that password reset requests are only issued to verified and approved organizational emails, limiting email access to a corporate domain improves security and lowers the possibility of external assaults.
5. Is it possible for WSO2 IS to manage several email domains under one tenant?
6. It is possible to set up WSO2 IS to support numerous email domains per tenant, which enables customizable email management settings.
7. What occurs if an incorrect email address is typed in while trying to reset your password?
8. To stop enumeration attacks, the system can be set up to either quietly reject the request or alert the user right away using frontend validation if an invalid email is input.
9. How do I update the WSO2 IS email validation logic?
10. Changing the regex settings in the user store administration dashboard or implementing unique adaptive authentication scripts are the usual methods for updating the email validation logic.

Protecting User Information and Functions

Strict validation procedures must be established in WSO2 IS in order to preserve strong security and operational integrity. Verifying email addresses prior to dispersing password reset links enables firms to avert potential security breaches and stop unwanted access. By putting these safeguards in place, administrators and users may work in a safer environment that adheres to identity management and cybersecurity best practices while also protecting user data.
