So coming from the Windows world, certificates are kind of a pain. You have to generate a certificate request from a trusted authority, then sign the certificate, and manually install it on the server. Plus, if you are using a 3rd party to do it and not your own domain then you will have to repeat this process probably once a year. Oh yeah, those SSL certificates are not free either as there is an associated cost with it.
Well, I figured out how to add in SSL, for free, on my AWS Lightsail instance. Amazon has really good documentation and if you follow the guide at https://lightsail.aws.amazon.com/ls/docs/en_us/articles/amazon-lightsail-enabling-https-on-wordpress it will show you step by step how to do it.
Super cool stuff. Set and forget with security and for free.
