How to Install SSL on a Domain in Plesk

This guide uses Let’s Encrypt (free SSL), which is integrated into Plesk.

✅ Step 1: Log in to Plesk

Go to:

https://your-server-ip:8443

Login with your Plesk credentials.

✅ Step 2: Go to Websites & Domains

From the left menu, click:

Websites & Domains

Find the domain you want to secure.

✅ Step 3: Click SSL/TLS Certificates

Under your domain name, click:

SSL/TLS Certificates

In newer Plesk versions, this might be named SSL/TLS or available directly as Let's Encrypt.

 

✅ Step 4: Click Install Let's Encrypt

Click the “Install” or “Get it free” button under Let's Encrypt.

Fill in:

• Email address (used for expiration reminders)

• Check:

  • ✅ Secure the domain

  • ✅ Secure www subdomain

  • ✅ Secure webmail (optional)

Click Install.

✅ Step 5: Done!

SSL will be installed and automatically configured for your domain.

You can now access your domain via:

https://yourdomain.com

Auto-Renewal

Let’s Encrypt in Plesk will automatically renew SSL every 90 days.
