Frequently Asked Questions

What is an SSL certificate?

An SSL certificate encrypts the data transmitted between a user's browser and the web server, ensuring privacy and security.

Why does the tool say the chain is incomplete?

This means your server is not serving the intermediate certificates required for browsers to trust the root certificate authority.

What happens when an SSL certificate expires?

Browsers will display a prominent security warning to users, preventing them from accessing the site safely.

Is it safe to enter passwords on a site without SSL?

No. Without SSL, data is sent in plain text, meaning anyone on the network could intercept your password.
