The default WordPress login page shows the WordPress logo, and when clicked, it links to wordpress.org. If you’re building a custom site or branding a client’s website, it’s a great idea to change this link to point to your site’s homepage or any custom URL.
To Change the Logo URL or Logo Title on WordPress Login Page Use Below Code.
Add code to your child theme’s functions.php file or via a plugin that allows custom functions to be added, such as the Code snippets plugin. Avoid adding custom code directly to your parent theme’s functions.php file as this will be wiped entirely when you update the theme.
