How to Customize WordPress Login Page Without Plugin

Plugin helps you add features to your login page, but it’s also possible to customize WordPress login page without plugin.

Don’t worry young padawan, it’s super easy!


Change the Login Logo in WordPress

In this simple step-by-step tutorial, I will guide you to change the WordPress logo on your login page. Enjoy!


1. Put your custom logo image to your /your-wp-theme/img folder.

2. Use the login_enqueue_scripts hook to insert CSS into the head of the login page so WordPress can loads your custom logo. Put this code into your /your-wp-theme/functions.php :


// Custom logo login page 
function my_login_logo() { ?> 
<style type="text/css"> 
body.login div#login h1 a { 
background-image: url(<?php echo get_stylesheet_directory_uri(); ?>/img/your-custom-logo.png); 
background-size: 200px auto; 
background-position: center; 
width: 300px; 
height: 70px; 
padding-bottom: 110px; 
<?php } 
add_action( 'login_enqueue_scripts', 'my_login_logo' );


3. Change “your-custom-logo.png” with your image file. You can also adjust size, width, height value to fit your need.

4. Open your login page, and press ctrl+shift+R, and see your shiny logo… 🙂

Add reCaptcha As Additional Security Measure

Besides the logo, you can also add a reCaptcha as an additional security layer to your WordPress.

Just like other security measures like 6 WordPress security plugins and 5 tips to make WordPress secure, this will help the malicious hacker away.

login page with reCapthca – sc:

Follow this step-by-step tutorial to implement a reCaptcha to your WordPress login page.

  1. Get reCaptcha API keys
    – go to the reCaptcha website ( > sign in with your Google account.
    – register new site by providing label and domain
    – note down the site key and secret key generated by reCaptcha
  2. Access your WordPress theme’s directory and locate the functions.php file > open the functions.php file in a code editor
  3. Add the following script

function add_recaptcha_to_login_form() {
$site_key = 'YOUR_SITE_KEY';
wp_register_script('google-recaptcha', '');
echo '<div class="g-recaptcha" data-sitekey="' . $site_key . '"></div>';
}add_action('login_form', 'add_recaptcha_to_login_form');function verify_recaptcha($user, $password) {
// Add the code for reCaptcha response validation here
// This function should validate the reCaptcha response during the authentication process
// It should check the response and return the appropriate result or error message
add_action('login_form', 'add_recaptcha_to_login_form');
add_filter('authenticate', 'verify_recaptcha', 10, 2)

Make sure to replace ‘YOUR_SITE_KEY‘ with your actual reCaptcha site key obtained from the reCaptcha website.

With this code snippet, the reCaptcha widget will be added to the login form, and the verify_recaptcha() function will handle the validation of the reCaptcha response during the authentication process. This combination provides both the display of the reCaptcha widget and the necessary security validation.

Now that you had added a recaptcha to your login page, it will protect your WordPress against brute force attacks.

Other Elements of WordPress Login Page that You Can Change

Besides the login logo and adding a reCaptcha to your login page, there are many other elements that you can add or modify.

A login page is an important component as it serves as the gateway for administrators and users to access the site’s backend.

There are plugins that can help you to modify the login page, but you can keep your website to be lean and load faster without bloated plugins.

  • Change the form appearance
    Not only the background image, the form’s color, fonts, and size can also be modified by targeting relevant CSS selectors in your theme’s style.css file
  • Implement a custom login error message
    Add a code snippet to functions.php or your theme’s custom functionality file to display personalized error messages on the login page.
  • Redirect users after login
    Modify the login behavior by redirecting users to a specific page or a custom URL upon successful login.
  • Customize the login URL
    Change your wp-admin login address to a unique and less predictable address manually
  • Utilize custom login page templates
    Create a custom login page template by duplicating and modifying the default login.php file in your theme’s directory

Remember to create a child theme before making any modifications to your theme files. Child themes help to avoid losing changes during theme updates.

A child theme is a theme that inherits the functionality and styling of its parent theme. when you want to customize your WordPress theme, child themes will give you these benefits:

  • Preserve Modifications
