When I was looking into the streaming side of things I set up an overlay image which could be toggled with a hotkey to hide my screen (it actually also hid my desktop scene too in case the image didn't load or whatever)

My main precaution though was separating dev/prod and never looking at prod stuff online. Worst case someone could spin up some guff in my dev/test account until I can cycle the credentials

In my case the separation also included a different system user on my computer for stream work. Possibly overkill but why risk it when the costs are so low?

I can't see myself trusting a key blurring app if I'm honest. Rather fix the issue earlier in the process than rely on something that would probably break on edge cases (word wrap enabled? Here's the key but it's in two parts, that sort of thing)

I agree I'd probably not trust it either, I'd be tempted to buy a completely seperate machine just out of paranoia
