    Is there a way to pre-populate the username / create the user name using the registrant’s first name and surname? Either by hiding the field or making it non-editable?

    Hi @colinsp

    You can try this code snippet:

    add_filter("um_add_user_frontend_submitted", function( $args ){
        $args['user_login'] = $args['first_name'].".".$args['last_name'];
        if ( username_exists( $args['user_login'] ) ) {
            UM()->form()->add_error( 'first_name', __( 'Username is already linked to another account', 'ultimate-member' ) );
        return $args;

    You can add the code snippet in your theme’s functions.php file or use the Code Snippets plugin: https://wordpress.org/plugins/code-snippets/
