Securing your website with an SSL/TLS certificate is essential for protecting user data and improving search engine rankings. Let's Encrypt provides free, automated certificates that are trusted by all major browsers. This guide explains the basics for hosting customers.

Let's Encrypt uses the ACME protocol to automate certificate issuance and renewal. Most hosting control panels (like cPanel or Plesk) have built-in integration, making setup straightforward:

• Access your control panel and find the SSL/TLS section.
• Look for an option labeled "Let's Encrypt", "Free SSL", or "AutoSSL".
• Select the domain you wish to secure and click install or generate.

The system automatically handles domain validation, certificate installation, and configuration. For manual setup via SSH (often needed for custom configurations), you can use the Certbot client. The key advantage is automatic renewal; certificates expire every 90 days, but the automation ensures your site stays secure without manual intervention.

Remember, a valid certificate requires your domain to be properly pointed to your hosting server's nameservers or IP address. If you encounter issues, check your domain's DNS settings first. Using Let's Encrypt is a cost-effective and reliable way to enable HTTPS and the padlock icon for your visitors.
