A WordPress website should use HTTPS for every page, not only for checkout or login pages. The good news is that you usually do not need to buy a separate SSL certificate. Many hosting providers and services provide publicly trusted certificates at no additional certificate cost.
SSL vs. TLS: what does your website actually use?
SSL is the older name people still use, but modern websites use TLS (Transport Layer Security). A TLS certificate helps establish an encrypted HTTPS connection between a visitor and the website. It protects data in transit from being read or modified while it travels between the two endpoints.
A certificate does not make a WordPress site secure by itself. You still need secure passwords, updates, appropriate access controls, backups, malware protection and a properly configured hosting environment.
Why HTTPS matters for WordPress
- It encrypts traffic between the browser and the website.
- Browsers can warn visitors when a site is served insecurely over HTTP.
- HTTPS is expected for modern websites, especially pages that handle logins, forms or payments.
- It supports secure integrations, APIs and other modern web features that require HTTPS.
How to get free SSL/TLS for WordPress
1. Use your hosting provider’s included certificate
Start here. Many managed WordPress and conventional hosting providers can provision and renew a publicly trusted certificate automatically. The exact dashboard and setup depend on the host, so look for an SSL, TLS, Security or HTTPS section rather than installing a separate WordPress plugin simply to obtain a certificate.
2. Use Cloudflare Universal SSL
Cloudflare currently provides free, publicly trusted Universal SSL certificates for domains that are added to and activated on Cloudflare. Cloudflare handles issuance and renewal for the edge certificate. Universal SSL on the free plan is Domain Validated (DV) and covers the root domain and first-level subdomains in a standard full setup.
If Cloudflare is in front of your WordPress site, do not assume the visitor-to-Cloudflare connection is enough. For end-to-end encryption, the connection from Cloudflare to the origin should also be encrypted. Cloudflare recommends Full (strict) when the origin has a valid certificate.
3. Use Let’s Encrypt through your host
Let’s Encrypt is a nonprofit certificate authority that provides publicly trusted certificates free of charge. Many hosting environments integrate certificate issuance and renewal into their control panels. If your host exposes a Let’s Encrypt option, using that integration is generally easier than manually creating and installing certificates.
4. Use an automated ACME client when you manage the server
If you administer your own VPS or web server, an ACME client can request and renew certificates automatically. This is more technical than a managed-hosting setup, but it gives you control over the certificate lifecycle.
Do you need a WordPress plugin for SSL?
Not necessarily. A WordPress plugin can help with tasks such as fixing mixed-content references or managing specific HTTPS-related settings, but the TLS certificate itself is normally issued and installed at the hosting, server or reverse-proxy layer.
After HTTPS is working, check WordPress settings, canonical URLs, redirects, images, scripts, fonts and other resources for mixed-content problems.
What type of certificate does a typical WordPress site need?
For most websites, a Domain Validated (DV) certificate is sufficient. OV and EV certificates provide additional organization-validation processes, but the choice should be driven by the site’s requirements rather than assuming that a more expensive certificate automatically provides stronger encryption.
Wildcard and multi-domain certificates can be useful when one certificate needs to cover multiple hostnames, but your hosting environment may already handle this automatically.
How to enable HTTPS after the certificate is active
- Confirm the certificate is active for the exact domain and required subdomains.
- Make sure WordPress Address and Site Address use https://.
- Set a single HTTP-to-HTTPS redirect at the appropriate server or proxy layer.
- Check for mixed content such as HTTP images, scripts, stylesheets or fonts.
- Test the homepage, forms, login, checkout and important landing pages.
- Confirm canonical URLs and XML sitemaps use HTTPS.
- Check Search Console and analytics configurations after the migration if the site previously used HTTP.
Common SSL/TLS mistakes
- Using Flexible SSL incorrectly: Encrypting only the visitor-to-proxy connection does not provide end-to-end encryption.
- Forgetting redirects: The certificate can be valid while HTTP pages remain accessible.
- Leaving mixed content: HTTPS pages can still load insecure resources.
- Installing multiple SSL plugins unnecessarily: Overlapping HTTPS or redirect logic can create loops and conflicts.
- Ignoring renewal: A certificate that expires can take the site offline or trigger browser warnings unless renewal is automated.
- Uploading confidential files to unknown services: Certificate setup should not require handing sensitive website data to an unrelated third party.
How to verify your WordPress site after enabling HTTPS
Open the site in a private browser window and test representative pages. Check the browser’s connection information, confirm there are no certificate warnings, inspect the page for mixed-content errors, and test forms and authenticated areas. If you use a CDN or reverse proxy, verify both the edge certificate and the connection to the origin.
Bottom line
For most WordPress sites, the simplest route to free SSL/TLS is to use the certificate included by the hosting provider. If your site uses Cloudflare, Universal SSL is another straightforward option for the visitor-facing connection. Let’s Encrypt remains a strong choice when your hosting or server environment integrates with it. The important part is not merely obtaining a certificate, but configuring HTTPS correctly, redirecting HTTP traffic, eliminating mixed content and maintaining encryption through the full delivery path.
