Every WordPress login page shows the same thing: the WordPress logo, a login form, and a link back to wordpress.org. For client sites, this is a branding miss. Your client logs in daily and sees WordPress branding instead of their own.

Replacing the logo takes 5 lines of CSS. No plugin needed.

What is the login page logo?

The WordPress login page (wp-login.php) displays the WordPress “W” logo above the login form. It’s an

element with a background image set via CSS. Clicking it goes to wordpress.org.

You can replace both the image and the link destination.

The quick fix

// Custom login logo
add_action( 'login_enqueue_scripts', function() {
    echo '<style>
        #login h1 a {
            background-image: url(' . esc_url( get_theme_file_uri( 'images/logo.png' ) ) . ');
            background-size: contain;
            width: 100%;
            height: 80px;
        }
    </style>';
});

// Change logo link to your site
add_filter( 'login_headerurl', function() {
    return home_url( '/' );
});

// Change logo hover text
add_filter( 'login_headertext', function() {
    return get_bloginfo( 'name' );
});

Upload your logo to your theme’s /images/ folder and adjust the height value to match your logo’s proportions. Use a transparent PNG for best results.

FAQ

### What size should the logo be?

Aim for 320px wide maximum (the login form width) and any reasonable height. Use a transparent PNG or SVG. Retina displays benefit from 2x resolution images.

### Does this change the logo in wp-admin?

No. The admin bar logo (WordPress “W” in the top-left) is separate. This only affects the login page.

### Will a theme update overwrite my custom logo?

If you added the code to your parent theme’s functions.php, yes. Use a child theme, a code snippets plugin, or OvKit to make the change persistent.
