How do to install a free SSL ( Lets Encrypt )?

Here’s a step-by-step guide to installing a free SSL certificate from Let’s Encrypt in Plesk. This makes your website secure (adds the padlock in the browser), and it’s free forever with auto-renewal. No technical skills needed!

Step 1: Log in to Plesk

• Open your browser and go to your Plesk login page (e.g. https://yourdomain.com:8443).

• Enter your Username and Password.

• Click Log in.

Step 2: Go to “Websites & Domains”

• In the left menu, click Websites & Domains.

• Find the domain name you want to secure with SSL.

• Look for the Let’s Encrypt button directly under that domain.

If you don’t see it immediately, continue with Step 3 below.

Step 3: Click “Let’s Encrypt”

• Click the Let’s Encrypt button.

  • If it's not on the main screen, click SSL/TLS Certificates, then select Let’s Encrypt from there.

• This opens the Let’s Encrypt setup screen.

Step 4: Fill in the certificate details

• Enter your email address (for renewal notifications).

• Check the following options:

  • Secure the domain (yourdomain.com)

  • Secure the "www" subdomain (www.yourdomain.com)

  • Secure webmail (webmail.yourdomain.com) – optional

Step 5: Click “Get it Free” or “Install”

• Click the Get it Free button (or Install, depending on your Plesk version).

• Plesk will now:

  • Contact Let’s Encrypt.

  • Create your SSL certificate.

  • Install it automatically.

This usually takes less than a minute.

Step 6: Set HTTPS redirect (optional but recommended)

To make sure all visitors are redirected to the secure (HTTPS) version of your site:

1. In Websites & Domains, click Hosting Settings.

2. Scroll down to Security.

3. Check:

   • SSL/TLS support

   • Permanent SEO-safe 301 redirect from HTTP to HTTPS

4. Click OK to save.

That’s it! Your website now uses a free SSL certificate from Let’s Encrypt. It will auto-renew every 90 days, so you don’t need to do anything in the future.
