Hi,
That text is located in the theme folder template file /atelier/woocommerce/myaccount/my-account.php.
You can edit the text:
<?php
printf(
__( 'Hello <strong>%1$s</strong> (not %1$s? <a href="%2$s">Sign out</a>).', 'swiftframework' ) . ' ',
$current_user->display_name,
wp_logout_url( get_permalink( wc_get_page_id( 'myaccount' ) ) )
);
printf( __( 'From your account dashboard you can view your recent orders, manage your shipping and billing addresses and <a href="%s">edit your password and account details</a>.', 'swiftframework' ),
wc_customer_edit_account_url()
);
?>
Thanks,
David.
