Disable username login and force email login

and how to add GDPR privacy policy checkbox when user comment on Woodmart Blog
for following GDPR before posting there should be checkbox that is required to mark

1. i figure out how to set checkbox GDPR checkbox..
2. i also resolve how to force email login, here is snipped code so you can help others when they ask
there is also ability to allow certain user to continue login with username if you add their username on list

// Function to authenticate using email only with exceptions
function custom_email_login_authenticate($user, $username, $password) {
    // Check if the username is in the exception list
    $allowed_usernames = array(
        'testuser',        // Add usernames you want to allow to log in using username
        'specialuser',  // Add more usernames as needed
    );

    if (in_array($username, $allowed_usernames)) {
        return wp_authenticate_username_password(null, $username, $password); // Allow login with username
    }

    // If the username is not in the exception list, enforce email login
    if (!is_email($username)) {
        return new WP_Error('invalid_email', __('Please login using email not username'));
    }

    // Get user by email
    $user = get_user_by('email', $username);

    if ($user) {
        $username = $user->user_login;
    }

    // Continue with the standard authentication process
    return wp_authenticate_username_password(null, $username, $password);
}
add_filter('authenticate', 'custom_email_login_authenticate', 20, 3);
