When it comes to running a professional and visually consistent WordPress website, every detail counts. One often overlooked aspect of customization is the login page logo.

This simple tweak can help you to add your brand logo to the default WordPress login page. Also, changing the default login URL can increase your website security sometimes.

Preparing Your Logo

Before you start customizing, ensure you have a well-designed logo ready. Here are some tips:

• Logo Dimensions: Check the ideal dimensions for your logo. A square logo often works well. But I recommend creating a logo in 720x144 dimensions.

• File Format: Use common image formats like PNG or JPEG.

Uploading Your Logo

1. Access Your WordPress Dashboard: Log in to your WordPress admin dashboard.

2. Navigate to Media Library: In the left sidebar, go to "Media" and then "Library."

3. Upload Your Logo: Click the "Add New" button and upload your logo. Once uploaded, click on the logo to view its details.

4. Copy the URL: Copy the URL of the logo from the "Copy Link" section. You'll need this URL to set your custom logo.

Editing functions.php (or Using a Plugin)

Now that you have your logo ready and its URL copied, it's time to customize the login page. There are two primary methods for changing the login page logo:

Method 1: Editing functions.php

• Open your theme's functions.php file, typically located in your theme directory.

• Add the following code at the end of the file, replacing 'YOUR_LOGO_URL' with the URL you copied earlier:

function custom_login_logo() {
    echo '<style type="text/css">
        #login h1 a, .login h1 a {
            background-image: url(' . get_stylesheet_directory_uri() . '/YOUR_LOGO_URL);
            height: 100px; /* Change the height as needed */
            width: 100%; /* Use 100% width for responsiveness */
            background-size: contain; /* Adjust this property as needed */
        }
    </style>';
}

add_action('login_enqueue_scripts', 'custom_login_logo');

• Save the changes to the functions.php file.

Testing Your Customized Login Page

It's crucial to test your customized login page to ensure everything looks as expected. Log out of your WordPress admin panel or open an incognito window, and visit your login page. Test it on various devices to ensure responsiveness.

Customizing the Logo Appearance

You may want to tweak the appearance of your custom logo further. You can do this by adjusting the CSS styles in the code you added to functions.php or through the plugin settings. Play around with properties like background-size and background-position to achieve your desired look.

Method 2: Using a Plugin

Alternatively, you can achieve the same result using a plugin. Just navigate to Plugins> Add new. Now type "Change Login Page Logo" keyword. Feel free to install any plugin you like. Just make sure to check recent updates and good ratings.

Troubleshooting Common Issues

If you encounter issues during the customization process, here are some common problems and solutions:

• Logo Not Showing: Double-check the URL and make sure it's correct in your code or plugin settings.

• Styling Issues: Adjust the CSS properties to fine-tune the logo's appearance.

• White Screen: If you see a white screen or errors after editing functions.php, make sure there are no syntax errors in your code. You better make a copy of your function.php file or work on a child Theme.
