How do I change the logo on the login page?

The question:

Right now, my login page shows the WordPress logo. How do I change it to my logo?

The Solutions:

Below are the methods you can try. The first solution is probably the best. Try others if the first one doesn’t work. Senior developers aren’t just copying/pasting – they read the methods carefully & apply them wisely to each case.

Method 1

Here is a pretty simple approach to changing the logo. Mark Jaquith of WordPress released a plugin that allows you to upload an image which will be shown on the login page instead of the WP logo.

Customize the WordPress Login Screen Logo

Method 2

I’d personally do it like this..

Hook on login head and inject some extra CSS

Hook in late, and your styling will go in after the login css inclusion, so you’re less likely to need !important to force styles.

add_action( 'login_head', 'custom_login_css', 99999 );

function custom_login_css() {
    ?>
    <style type="text/css">
    h1 a {
        background: url(path/to/your/image/example.jpg) no-repeat top center;
    }
    </style>
    <?php
}

One function, one hook, job done..

Hope that helps…

If you want to go a step further and totally seize control of the login CSS keep reading, else just ignore what follows, i’m going to post it anyway, for the sake of others wanting to totally hijack login CSS..

Intercepting the enqueue

Hook onto style_loader_src declaring 2 parameters for the callback function.

First parameter is given the stylesheet’s url or src.
The second is a given enqueue’s handle, eg. colors, login, global..and so on..

The second variable helps the filter determine what enqueue is being called, and updates the src when it matches the login handle.

add_filter( 'style_loader_src', 'hijack_login_src', 10, 2 );

function hijack_login_src( $src, $handle ) {
    if( 'login' == $handle )
        $src = get_bloginfo( 'stylesheet_directory' ) . '/customlogin.css';
    return $src;
}

I used stylesheet_directory in the get_bloginfo() call to ensure we’re pointing at the right directory for child themes to.

Styling the login

Create the file referenced in the above function inside your theme’s folder, so following the example customlogin.css.

Copy the code from this pastebin, paste it into the newly create CSS file and save.
The code in the pastebin is basically a copy of the login.dev.css from WP 3.0.3, the difference with taking this approach is having full control over the CSS for the login without need for overrides in your styling.

Now simply make whatever changes you like inside that file.

One caveat to note here, is that the login file uses relative paths for images, so the stylesheet as is will point at non-existant images.
However as the stylesheet is now in your theme directory, you can use a relative path to your theme’s image directory, giving you two easy solutions.

Copy the original images from wp-admin/images/ into your theme’s image folder and use a relative path(see below).
Set the styles to use your own images in your theme’s image folder using a relative path, eg. images/someimage.jpg.

Method 3

Lots of plugins and variations – custom login wordpress – Google Search – but basically:

Goes in your theme’s functions.php file:

function custom_loginpage_logo_link($url)
{
return get_bloginfo('wpurl');
}
function custom_loginpage_logo_title($message)
{
return get_bloginfo('name');
}
function custom_loginpage_head()
{

$stylesheet_uri = get_bloginfo('template_url')."/login.css";
echo '<link rel="stylesheet" href="'.$stylesheet_uri.'" rel="nofollow noreferrer noopener" type="text/css" media="screen" />';
}
add_filter("login_headerurl","custom_loginpage_logo_link");
add_filter("login_headertitle","custom_loginpage_logo_title");
add_action("login_head","custom_loginpage_head");

And make a file called login.css for your theme directory and make CSS changes there:

html,
body.login {background-color: #464646;}
#login h1 a {height:160px;background: url(images/mylogo.jpg) no-repeat top center;}
#login .message {display:none;}
#login form {background-color: #c2c2c2;}
#login label {color: #111;}
#login input {border: 1px solid #999;}
.login #login p#nav a:link,
.login #login p#nav a:visited,
.login #login p#nav a:hover,
.login #login p#nav a:active {text-decoration:none; color: #fff !important}
#nav {color: #fff; font-weight: bold}

This article by WPEngineer should get you started on changing the logo, name, and link of your WordPress login page.

Method 5

Copy and paste the code in your theme function.php file.

function change_my_wp_login_image() {
    echo "
        <style>
            body.login #login h1 a {
                background: url('".get_bloginfo('template_url')."/images/your_image_name') 8px 0 no-repeat transparent;
                background-position: center;
                height: 100px;
                width: 320px;
                background-color: #E48C07;
            }
        </style>
    ";
}
add_action("login_head", "change_my_wp_login_image");
