The WordPress login is one of the most used pages in the WordPress admin. Though simple and clean, it is heavily branded WordPress. However, most new users and clients do not need to know about the underlying software your site runs on.

If you are handing off the site to a client, or if you are running a member site where most users will be visiting the login screen, it is a good idea to add your own style to the page to make it more inviting and align it better with your site. You can do this by adding your own logo, changing the typography and color palette of the form and background, and appending useful links underneath the form. When customized properly, the login page can be a useful entry point for your users, welcoming them to your site and brand.

Fortunately, WordPress gives you the ability to customize a good amount of the login page with just a little code. In this article, we’ll walk through how to customize the login screen with a few WordPress hooks in your theme file, then go over a few plugins that can help with the task.

Customizing the WordPress Login In Your Theme

The easiest way to make changes to the WordPress login page is to add some code directly to your active theme. Most of this code will live in the functions.php file. This is a required file, so any code used here will work in any theme. I would recommend making these changes in a testing environment first before moving it to your live site.

The first thing to do is open your theme’s directory and create a new folder in the root called login. We’ll use this folder to hold the images and CSS stylesheets we’ll be using throughout the article.

Next, open up the functions.php theme file in the editor of your choice. This file contains extra hooks, functions and filters necessary for your theme to work. It is where scripts and styles are added to a theme, customization options are defined, and extra back-end functionality is bundled in. We will be adding all of our code to the bottom of this file. Any edits made to this file will only take effect to the theme it belongs to. If you choose to activate another theme later on, you will have to migrate this code to the new theme’s functions.php file.

Changing the Login Logo

One of the simplest changes you can make to the login screen is to swap out the default WordPress logo at the top of the form for your own, so that it fits in with the overall look of your site.

The first thing to do is save your logo image in the login folder you created. The default size for this image is 80 pixels x 80 pixels. Your image doesn’t have to be exactly that size, but make sure it is square so that it fits the dimensions. This can be changed as well, but requires some additional code provided later in the article. I would also recommend saving a transparent PNG file, so the image works on any background.

Simply save your logo image as logo.png to the login directory you created. Then, at the bottom of your functions.php file, add this code.

function my_loginlogo() {
  echo '
    h1 a {
      background-image: url(' . get_template_directory_uri() . '/login/logo.png) !important;
    }
  ';
}
add_action('login_head', 'my_loginlogo');

We are using the login_head WordPress action here to append a small bit of CSS to the section of the login screen’s HTML. From there, we are changing the background image of the h1 tag to our own custom logo. Make sure to include the “!important” flag in your CSS so that the default logo image is overwritten.

After adding this code, you will see your own logo appear on the page, directly above the login form. So far so good.

Changing the Logo Image URL

By default, this logo image still links to “https://wordpress.org”. Chances are, you’ll want to direct this link elsewhere, either to some useful documentation or your own site’s homepage.

To change this link, you just need to add a few lines of code to the bottom of your functions.php file.

function my_loginURL() {
    return 'https://elegantthemes.com';
}
add_filter('login_headerurl', 'my_loginURL');

This time, we are using the login_headerurl filter in order to change the URL of the logo image. Make sure to replace “https://elegantthemes.com” with your preferred URL.

It’s also probably useful to change the title tag of this link, so that when a user hovers over it, they will see a proper name displayed. By default, this tooltip displays “WordPress.” To modify this tooltip, add this block of code.

function my_loginURLtext() {
    return 'Elegant Themes';
}
add_filter('login_headertitle', 'my_loginURLtext');

Again, change “Elegant Themes” to the name of your site.

Adding a Custom Stylesheet

The login screen is looking okay, but there are a few more style changes that still need to be added. For one thing, the logo is still fairly small. I’d also like to change the colors of the background and form elements to match the Elegant Themes brand a bit more. Finally, the typography of the form can also be tweaked a bit.

In order to accomplish this, we are going to add a new CSS stylesheet to house the CSS styles we want to apply to the page, then enqueue it to apply it to the login page. For this step, some basic knowledge of CSS will be required.

In the login folder you created add a new file called login_styles.css. Then, open this file up in the editor of your choice. You can add any kind of CSS to this file, but you’ll need to conform to the HTML markup produced by WordPress. For a full list of classes and IDs for you to hook into on the login page, visit the WordPress codex. In order to make the enhancements I want, I’ll add this chunk of code to my CSS file.

/* Change background color and font family */
body {
  background: #f8fafa;
  font-family: Arial,Verdana,sans-serif;
}

/* Change Width and Height of Logo Image + Add Custom Image File */
.login h1 a {
  background-image: url(logo.png);
  width: 213px;
  height: 97px;
  background-size: 213px 97px;
}

/* Add a few changes to the color and style of form itself */
.login label {
  color: #454545;
  display: block;
  margin-bottom: 1em;
  font-weight: bold;
}

.login form .input {
  font-weight: normal;
}

.login #backtoblog a, .login #nav a {
  color: #4da28f;
}

.wp-core-ui .button-primary {
  background: #4da28f;
}

Let’s step through these styles a bit. First, I added a background color and font family to the body tag, to change the general typography of the page, and the main background. Next, I added the code from our function in the first step straight into the stylesheet, but tacked on additional properties for the width, height and background size. This will change the aspect ratio of the logo image, and make it larger on the page. Lastly, I changed the colors and styles on the login form itself, to bold the “Username” and “Password” fields, and change the color of the footer links and buttons.

In order to actually have these changes take effect, you will need to enqueue this stylesheet using the login_enqueue_scripts action. Go back to your functions.php file and add this small block.

function my_logincustomCSSfile() {
	wp_enqueue_style('login-styles', get_template_directory_uri() . '/login/login_styles.css');
}
add_action('login_enqueue_scripts', 'my_logincustomCSSfile');

You can also remove the my_loginlogo function from the first step, as this code has now been incorporated into the stylesheet.

There is a lot more that can be done with custom CSS if you want to dig in, but already quite a bit has been customized to match the style of our site.

Adding a Custom Link Under Form

Below the login form, there are two links. The first is for users who lost their password, and the other is a link back to your main site. If you have open registration, there will also be a Register link here. These are useful enough, but I want to provide a bit more value to my users by adding a link to the Elegant Themes blog for quick access. If you are managing a site for clients, this might be a good place to put a link to documentation or a support form.

To append a link to the footer of the page, we use the login_footer action in our functions.php file.

function my_loginfooter() { ?>
	

	If you have any questions, visit our blog
        
	
<?php }
add_action('login_footer','my_loginfooter');

The link directs users to the Elegant Themes blog, but make sure to change the URL and corresponding text to something relevant for your users. I also added a few custom styles to match the rest of the page.

So, with a little bit of effort, your login page can incorporate your brand’s style and offer some useful information to users logging in. But there’s one final trick I’d like to share with you.

Redirecting Users after Login

By default, users are redirected to the WordPress admin after they login. But if you have a site with open registration, or a special area you want clients to be redirected to, this may not be the behavior you want. Using the login_redirect filter, you can redirect users anywhere on your site after they login.

function my_loginredrect( $redirect_to, $request, $user ) {
  if ( isset( $user->roles ) && is_array( $user->roles ) ) {
    if( in_array('administrator', $user->roles)) {
      return admin_url();
    } else {
      return site_url();
    }
  } else {
      return site_url();
  }
}

add_filter('login_redirect', 'my_loginredrect', 10, 3);

This might look a bit tricky, but that is simply because I’ve added in a few conditions for the redirect. First, the function checks the user’s role. If the user logging in is an administrator, they are redirected to the admin page (admin_url()) like normal, otherwise, they are directed to the site’s main homepage (site_url()). And as a final precaution, if all else fails, then users are directed to the homepage as well. These two URLs can be changed to direct to any page on your site, either by using WordPress directory shortcuts, or hard coding a link.

Helpful Plugins

All of the code outlined above is reusable on any theme you have installed. In turn, a few clever developers have created plugins that can do the heavy lifting for you, if you’d prefer to stay away from coding it yourself. The following plugins all tackle a different element of the login page, and they might be exactly what you need.

Custom Login

Custom Login lets you style every element on the login screen, one by one. You can upload custom background images for the body and login form, or a custom logo to replace the default WordPress logo. You can also customize the color of backgrounds, text and links. The plugin also allows you to inject custom CSS, HTML and Javascript into the page.

Uber Login Logo

If you are simply looking to change the logo on the login screen, you can use Uber Login Logo. It allows you to upload any image through it’s settings page, which it swaps in for the default WordPress logo. Keep in mind that only the logo is replaced, and that you have to conform to the default dimensions.

Sky Login Redirect

If you’re searching for a different way to redirect users after login, Sky Login Redirect takes an interesting approach. Instead of hardcoding a URL for users to be redirected to, they will simply be brought back to the page they were browsing before login. So if a user is reading a post of yours, then logs in, they will be brought immediately back to that article. In all extraneous cases, users are directed to the homepage. If you have a membership site, this is likely the most convenient flow for your users.

Go Forth and Customize

Modifying your login screen is a simple way to brand the WordPress admin and make it more approachable to your end users. Use it to provide helpful links to clients, enhance the login form, or just spruce the page up a bit to make users more comfortable with the login process.
