Common questions
- How do I check when my SSL certificate expires?
- Enter your website above and press Check. We read the live certificate and show the exact expiry date and how many days are left, with no signup.
- What does "not secure" mean in my browser?
- It usually means the certificate has expired, doesn't match the site's name, or isn't trusted. Our checker names the specific reason in plain language.
- Is this SSL checker free?
- Yes, completely, with no signup and no card. If you want us to keep watching your sites, you can add them to a free SSLCanary account.
- What's the difference between SSL expiry and domain expiry?
- The SSL certificate is what makes a site load over https; it renews every few months. The domain registration is your ownership of the name, usually renewed yearly. SSLCanary watches both.
