As you already know about the Password protected setting for your post or page. When your post or page is protected it will show “Protected” prefix before its title. If you want to change or remove that prefix just follow the below steps :-
/**
* Removes or edits the 'Protected:' part from posts titles
*/
add_filter( 'protected_title_format', 'remove_protected_text' );
function remove_protected_text() {
return __('Protected: %s');
}
/**
* Removes or edits the 'Protected:' part from posts titles
*/
add_filter( 'protected_title_format', 'remove_protected_text' );
function remove_protected_text() {
return __('%s');
}
