Integrating Let's Encrypt SSL Certificates with Plesk is a straightforward process that allows users to secure their websites with free SSL/TLS certificates. Let's Encrypt certificates are trusted by most browsers and provide encryption for secure communication between the server and clients. Here's a step-by-step guide on how to integrate Let's Encrypt SSL certificates with Plesk:

1. Access Plesk Control Panel:

   • Log in to your Plesk control panel using your administrator credentials.

2. Navigate to Websites & Domains:

   • Once logged in, navigate to the "Websites & Domains" tab from the top menu.

3. Select Domain:

   • Choose the domain for which you want to install the Let's Encrypt SSL certificate.

4. SSL/TLS Certificates:

   • Scroll down to the "Security" section and click on "SSL/TLS Certificates."

5. Add SSL/TLS Certificate:

   • Click on the "Add SSL/TLS Certificate" button to initiate the Let's Encrypt certificate installation process.

6. Enter Certificate Details:

   • In the "Certificate Name" field, enter a name for the certificate (optional).
   • Optionally, choose the "Secure the domain and all its subdomains" option if you want to secure both the main domain and its subdomains.
   • Click on the "Get it free" button to proceed.

7. Install Certificate:

   • Plesk will automatically generate and install the Let's Encrypt SSL certificate for your domain.
   • Once the installation process is complete, you will receive a confirmation message indicating that the certificate has been successfully installed.

8. Verify Certificate Installation:

   • You can verify the installation of the Let's Encrypt SSL certificate by checking the "Certificate Status" section, which should display "Certificate is valid."

9. Optional: Configure HTTPS Settings:

   • If necessary, you can configure HTTPS settings for your domain by enabling the "Permanent SEO-safe 301 redirect from HTTP to HTTPS" option. This will automatically redirect visitors to the secure HTTPS version of your website.

10. Verify SSL Installation:

    • Visit your website using the HTTPS protocol (e.g., https://www.yourdomain.com) to verify that the SSL certificate is installed correctly and that your website is securely accessible via HTTPS.

11. Renewal and Maintenance:

    • Let's Encrypt SSL certificates are typically valid for 90 days. Plesk will automatically renew the certificate before it expires, ensuring continuous SSL protection for your website. You can also manually renew or revoke the certificate if necessary.

By following these steps, you can easily integrate Let's Encrypt SSL certificates with Plesk and secure your websites with free and trusted SSL/TLS encryption. This helps enhance security, build trust with visitors, and improve SEO rankings by ensuring your website is accessible via HTTPS.
