Change the admin footer text

// Replace "Thank you for creating with WordPress" in the admin footer.
add_filter(
	'admin_footer_text',
	function () {
		return wp_kses_post( 'Site built and looked after by <a href="https://example.com/">Your Agency</a>. Need help? <a href="mailto:support@example.com">Email us</a>.' );
	}
);

What it does

Every admin screen ends with "Thank you for creating with WordPress". Agencies and freelancers often swap it for their name and a support link, so clients know who to contact.

Edit the text and links in the snippet. It goes through wp_kses_post(), so simple HTML such as links and bold text is allowed.

Good to know

• Replace the example links with your own website and email address.
