Yeah, there's ways around it for sure, so it's not the end of the world.
I'm not super technical though, so as my hosting provider uses Google for HTTPS authentication I'll just reluctantly stick with that for now. Of course I could have found a different provider, but I found it a somewhat difficult market to navigate. I'm enough of a rookie that part of me is just happy things seem to be working - when I set up the website a few months ago I kind of assumed HTTPS was some black magic stuff that I would never manage to implement.
