Hi there,

If you have enabled Use Email as Username in your site backend > Components > EasySocial > Settings > Users > Authentication https://take.ms/JHKd1 ,then it will show the email address. If you want to show the username as First Name Last Name then you need to disable Use Email as Username.

Still not showing First Name Last Name. Now it only shows username instead. https://monosnap.com/file/UMKdW8W5XouuAlj51tbppGjKS4hsj2

Hey there,

Sorry it's my mistake. The steps that I mentioned will help you to show the username instead of email address. To show the First Name and Last Name you can customize the email template:
components/com_easysocial/themes/wireframe/emails/registration/verify.php

Change the line 46 as below:

<?php echo JText::sprintf('COM_ES_EMAILS_HI_USER', $firstName . ' ' . $lastName); ?>

For your information, to do this you need make sure that your EasySocial version is 3.x and above.
