I am trying to change favicon in wordpress. For which i have uploaded image in media and in theme customisation, under site identity i used that image as a favicon.
You can make it programatically through functions.php
First, create a function that includes the path to your favicon
function add_favicon() {
$favicon_url = get_stylesheet_directory_uri() . 'your_path';
echo '';
}
Now, just make sure that function runs when you're on the login page and admin pages:
add_action('login_head', 'add_favicon');
add_action('admin_head', 'add_favicon');
