Let’s face it, the default WordPress login screen can be a bit boring and doesn’t reflect your site’s unique branding. Customizing the WordPress login page is a simple yet effective way to create a cohesive brand experience for your website. In this guide, I’ll show you how to customize the WordPress login page without using a plugin.

Understanding the Login Forms

The wp-login.php page handles four different forms, each of which can be customized:

1. Login Form
2. Lost Password Form
3. Reset Password Form
4. Register Form

Leveraging WordPress Hooks & Filters

WordPress offers a variety of hooks, functions, and filters that allow you to customize the login screen extensively. You can explore a comprehensive list of these tools here.

Adding Custom CSS & JavaScript

To change the appearance and behavior of the login page, you can add custom CSS and JavaScript using the login_enqueue_scripts hook. This will enable you to style the login page to match your site’s theme and add any interactive features you need.

add_action('login_enqueue_scripts', function () {
    wp_enqueue_style('custom-login', get_stylesheet_directory_uri() . '/css/custom-login.css');
    wp_enqueue_script('custom-login', get_stylesheet_directory_uri() . '/js/custom-login.js');
});

Changing the Login Url

By default, the logo on the login page redirects to wordpress.org. You can change this URL to redirect users to your homepage or any other URL that fits your needs.

add_filter('login_headerurl', function () {
    return home_url();
});

Customizing the Login Text

To modify the text that appears when users hover over the login logo, use the login_headertext filter. This is a great way to add a personal touch or include a call to action.

add_filter('login_headertext', function () {
    return 'Welcome to My Website';
});

Modifying the Login Page Title

You can also customize the meta title of the login page to better reflect your brand. This can be done using the ‘login_title’ filter.

add_filter('login_title', function ($login_title) {
    return 'Login to My Awesome Site';
});

Securing Login Error Messages

Default login form error messages can reveal whether a username exists in the system, which poses a security risk. To improve security, you can make the error messages more generic, preventing potential attackers from gathering information about your users.

/**
 * Customizing the login error message
 * 
 * @link https://developer.wordpress.org/reference/hooks/login_errors/
 * 
 * @return string
 */
add_filter('login_errors', function ($error) {
    $error = 'Invalid username or password.';
    return $error;
});

Additional Customizations

Beyond the basics, there are numerous other customizations you can implement to enhance the login experience:

Custom Background and Logo

Add a custom background and logo to the login page to align it with your site’s branding.

add_action('login_enqueue_scripts', function () {
    echo '
    <style type="text/css">
        body.login {
            background-image: url(' . get_stylesheet_directory_uri() . '/images/custom-background.jpg);
            background-size: cover;
        }
        .login h1 a {
            background-image: url(' . get_stylesheet_directory_uri() . '/images/custom-logo.png);
            background-size: contain;
            width: 320px;
            height: 80px;
        }
    </style>';
});

Custom Login Button

Style the login button to match your site’s theme.

add_action('login_enqueue_scripts', function () {
    echo '
    <style type="text/css">
        .login .button-primary {
            background-color: #0073aa;
            border-color: #006799;
            color: #fff;
            text-shadow: none;
            box-shadow: none;
        }
        .login .button-primary:hover {
            background-color: #005a8e;
            border-color: #004f7a;
        }
    </style>';
});

Custom Footer Text

Add a custom message or copyright notice in the footer of the login page.

add_action('login_footer', function () {
    echo '<div style="text-align: center; margin-top: 20px;">© ' . date('Y') . ' Your Website. All rights reserved.</div>';
});
