How do I get a free SSL certificate for my domain?
Using Let's Encrypt
Let's Encrypt provides free, automated, and open certificates. To get one, you need to prove control over your domain, typically by placing a file on your web server or adding a DNS record. The certificate is valid for 90 days, but you can set up automatic renewal with a client like Certbot.
Most shared hosting providers (e.g., SiteGround, Bluehost) include Let's Encrypt integration in their control panels, so you can enable SSL with a few clicks. If you manage your own server, you can install Certbot and run it to obtain and install certificates for your domains.
- Free of charge
- Automated renewal possible
- Widely trusted by browsers
- Requires domain validation
Other free options and considerations
Some hosting providers offer free SSL certificates from other CAs, such as cPanel's AutoSSL feature, which uses Let's Encrypt or Comodo. Cloudflare also provides free SSL for domains using their proxy service, though the encryption between Cloudflare and your origin server may need configuration.
While free certificates are great for most websites, they typically offer only domain validation (DV), not organization validation (OV) or extended validation (EV). For high-security sites, a paid certificate might be preferable. Also, free certificates usually don't come with warranties or support.
Common mistakes
- Forgetting to renew Let's Encrypt certificates every 90 days; setting up auto-renewal is crucial.
- Assuming free SSL works on all hosting plans; some older or budget hosts may not support it.
- Believing that free SSL is less secure; Let's Encrypt uses the same encryption standards as paid CAs.
