Thanks

for covering the importance of SSL certificates! If you need a certificate for your website, remember that you can always get a free cert from Let's Encrypt.

What is an SSL certificate, why is it important and how to get one?

An SSL certificate ensures that website the you're visiting hasn't been compromised. It also prevents your password from leaking in transit.
