To get to 100% HTTPS adoption, it has to be easy for every website operator to turn on HTTPS. Through usability testing, the Certbot team is making Certbot more helpful for more people.
The last few years have seen a meteoric rise in HTTPS adoption on the web. At this stage, complete adoption is a feasible goal. To get there, it's going to have to be easy for every operator behind every website to turn on HTTPS.
Certbot is EFF's tool for getting automated certificates from Let's Encrypt. Certbot makes getting certificates easier, but how much easier? And which groups of users get left behind?
The Certbot team ran usability studies to find out how people were conceptualizing and using tooling around HTTPS. This talk will cover our (often surprising) results, lessons we learned, and how we're using what we learned to make Certbot more helpful for more people.
