Frequently Asked Questions
Is the SSL certificate really free?
Yes. Certificates are signed by Let's Encrypt, a non-profit certificate authority, and are completely free. There are no hidden fees, no credit card and no mandatory account.
Why is the certificate valid for 90 days?
Let's Encrypt certificates last 90 days for security. You can renew for free with the same steps before expiry, and signed-in users get email reminders.
How do I get the certificate?
Enter your domain, verify ownership with a DNS TXT record or an HTTP file, then download the CRT, KEY, CA Bundle and PFX files as a ZIP once validation completes. The whole flow takes a few minutes.
Is this certificate trusted by browsers?
Yes. The Let's Encrypt root is trusted by all modern browsers and operating systems, so the padlock appears in the address bar.
Can I get a wildcard certificate?
Single domain plus the www subdomain are supported. Wildcard certificates require DNS validation and are on our roadmap.
Which servers can I use the certificate on?
cPanel, Nginx, Apache, IIS, Plesk and more. Our blog has step-by-step installation guides for each platform.
