So I'm checking out this [crappy] Home Automation tool because I couldn't get HomeAssistant to load on OSX Catalina. So I just needed anything free to see if my new Z-Wave USB hub worked. I installed Domoticz
After I set the [local] webserver password, this came up:

I'm like, wtf?
here's the default Aware login.

Think about how often you surf the web and find [basically] the exact same login screen used on different websites.
One had to be based off another - its too identical to be 2 random developers making the same screen.
But even "our" login page has weird CSS and code - Lots of extra stuff thats totally unnecessary for a login screen.
And the Page Source is massive - and I can't even figure it out - but the end result is remarkable.
Reminds me of a story...
I was showing Jake Wallace, brother of Codrin (the RanFab guy) one of my systems a while back. I connected to the site to login and Jake said "hold it - what was that - that looks like something I did for RanFab long ago"
And I said "Oh yeah, I stole that Login screen from RanFab." At least 2-3 years ago a cust wanted to upgrade the Login screen since outside peeps were connecting. So i tool the basics, altered the CSS transforms & some colors and its pretty nifty. LOL
PS _ Which, when you think about it, is a gaping black hole of knowledge surrounding Aware Login Screens. We are left to all basically re-create the wheel (and waste time/effort) to just dress up a login for a cust. Depending on how much you want to change it, its def. a bunch of hours down the rabbit hole [for many of us]. But thats another story.
