If you are running an ecommerce site, accepting credit cards, or passing information that needs to be encrypted, you’ll need to install an SSL certificate on your WordPress site. Having an SSL certificate will enable HTTPS and this ensures that no information is passed in plain text. In fact, we recommend all sites utilize HTTPS, as it has a lot of additional benefits beyond security. Follow the steps below on how to install SSL on your WordPress site.
How to Install SSL Certificate
You have three different options when it comes to installing an SSL (TLS) certificate on your WordPress site. Also see information on checking your SSL certificate, renewing, and removal.
- Option 1 – Install Free SSL certificate
- Option 2 – Install Custom SSL certificate
- Option 3 – Install SSL certificate with Cloudflare or Sucuri
- Check SSL certificate
- Renew SSL certificate
- Remove Custom SSL certificate
Still looking for that perfect WordPress host?
- Fully managed
- Secure like Fort Knox
- Free migrations
- Ultimate speed
- Daily backups
- Google Cloud Platform
- All domains/sub-domains need to be added manually on the dashboard
- Limitation of 100 sub-domains
- Let’s Encrypt certificates are domain validated only (they don’t have warranties)
- Limitations on domains with special characters
Login to your MyKinsta dashboard and click on the site you want to manage under “Your Sites.”
Click on “Tools” and under Enable HTTPS click on “Generate A Free HTTPS Certificate.”
In order for a certificate to be generated successfully you must have at least one live domain pointed at Kinsta. Then click “Next.”
You will then have an option to choose the domains on which you want an SSL certificate installed. If your site is http://domain.com and has a redirect from www to non-www, you will still want to select both for the HTTPS redirect. Click on “Generate Certificate.” (Note: You will need to add all of your domains prior to this from the MyKinsta dashboard, including any subdomains which require SSL)
And that’s it! It will take a few seconds or so to install and your site should be all secured.
Step 1 – Purchase SSL Certificate
Step 2 – Server Type
When purchasing a new SSL certificate, you are asked to provide the server type. The type of our web servers is Nginx, if that option is not available, then “Other” will work as well.
Step 3 – Generate CSR and Private Key
A CSR code will be needed by the SSL provider to create/sign the certificate file. For generating a CSR code and RSA key, please complete the following form: https://www.ssl.com/online-csr-and-key-generator/.
We recommend filling out every field, but at a minimum, you should fill in the following as seen in the example below:
- Common name (domain name)
- Email Address
- City / Locality
- State / County / Region
Note: For the common name field, if you are generating a wildcard certificate, you will need to input your domain name like
The form will generate you the private key file and the CSR. Make sure to save both of those as the certificate will be unusable without them.
Upload your CSR with your SSL provider to regenerate your SSL certificate (.cert).
Log in to the dashboard, click on a site, go to the Tools tab and click the “Add Custom HTTPS Credentials” button to get started.
To use custom credentials you will need to have a .key and a .cert file prepared. Then click “Next.”
You will then be able to add your private key and certificate. Note: Some customers will also want to add their intermediate certificate as well. Most SSL providers will email you a .crt file and a .ca-bundle file. Paste the contents of your .crt file in the “Certificate” section first and then the contents of the .ca-bundle file below it. You can use a text editor like Notepad or TextMate to open the certificate and bundle files. If you don’t have or know your intermediate certificate you can use a free tool like https://whatsmychaincert.com/ to generate it. Then click “Apply Certificate.”
Cloudflare and Sucuri are what are known as reverse-proxy services. You can think of them as a middleman. You point your DNS to them, and in turn they route your requests to Kinsta’s servers. Because of this, there are a few additional steps you need to take to ensure SSL certificates are properly installed.
For Those Using Cloudflare
Cloudflare allows two different arrangements for loading a site over HTTPS: flexible or full (or full strict).
- Flexible allows an HTTP (unencrypted) connection between Cloudflare and the Kinsta servers and does not require an SSL certificate.
- Full requires an HTTPS (encrypted) connection between Cloudflare and the Kinsta servers.
Here are the steps you should follow:
In Cloudflare, click into the “Crypto” tab and turn off SSL (it’s also recommended to set Cloudflare to development mode till the SSL is ready on the Kinsta side. You can do this from the quick actions on the overview dashboard.)
Once your SSL certificate has been successfully installed at Kinsta, set the crypto level at Cloudflare to Full or Full (Strict) so that the connection is encrypted all the way from the Kinsta server to the client’s browser.
Then purge the Cloudflare cache. And if you put your site into development mode, make sure to set it back to active.
For Those Using Sucuri
You must first contact their support and have them enable the setting to “forward certificate validation.” This allows HTTPS provisioning to complete successfully. You may then install Let’s Encrypt or a custom SSL certificate via the methods above.
After you have installed your SSL Certificate we recommend running an SSL check to verify that everything is setup correctly.
Follow the information regarding renewal of your SSL certificate.
Free SSL Certificates
Free SSL certificates (Let’s Encrypt) deployed via the MyKinsta dashboard are renewed automatically every 90 days. There’s nothing you need to do. However, if your site is behind a reverse-proxy such as Sucuri, you must contact their support and have them enable the setting to “forward certificate validation” which allows HTTPS renewals to complete successfully.
Custom SSL Certificates
If you have a custom SSL certificate, you’ll need to renew it with the SSL provider or domain registrar from which it was purchased. As long as it was renewed before it expires, there’s no need to re-upload it to the MyKinsta dashboard.
There might be some instances in which you need to remove an HTTPS certificate, whether it be Let’s Encrypt or your own custom SSL certificate. Perhaps you were testing an HTTPS migration or maybe you’re migrating your site to Let’s Encrypt certificates. To remove an HTTPS certificate, simply click on “Remove HTTPS Certificate” under Enable HTTPS in the Tools menu.
