Customizing the WordPress login logo is an easy way to align your site's login page with your brand, creating a seamless experience for users and clients alike. As experienced WordPress developers know, this small tweak builds trust and professionalism. Here's how to do it right.
Open your active theme's functions.php file—ideally in a child theme to protect against updates—and add this reliable code snippet:
function custom_login_logo() {
echo '<style type="text/css">
.login h1 a {
background-image: url(' . get_bloginfo('template_directory') . '/images/login_logo.png) !important;
}
</style>';
}
add_action('login_head', 'custom_login_logo');Next, upload a transparent PNG named login_logo.png to your theme's images folder (create it if needed). Adjust the file path in the code if you prefer a different name or location.
This method works consistently across themes. For advanced layouts, check out top custom WordPress login page resources.
