I think you want the screwdriver to seat as far down as possible so I would recommend you dig out the glue

The US missed out on both the Robertson screw head and the metric system!

If it is filled with glue then I would try scraping it out with the tip of a utility or xacto knife

1. Strong down force with the appropriate screwdriver (looks like it started out as a Phillips head) while turning the driver with a wrench. You need a square shaft in your screwdriver or clamp with vice grips.

2. Same, strong down force, but use a square driver ( Robertson screw). This can also be accompanied with a wrench.

3. Drill it out. This is pretty much the last resort as you will use a drill bit about the same size as the threads which will pretty much take the head of the screw off as you drill into the threads. The threads probably won’t come out but you will at least be able to open the case. I have had very little luck with screw extractors and they probably don’t come that small.

Strong down force is the main thing I have found to work when breaking loose pesky screws. Pushing down hard enough to prevent the bit from skipping to the next slot

I should have mentioned:

1. This is the first time I separated all the pieces by color/region before assembly and I was amazed at how much faster it went together.

2. Instead of doing the edges first I started at the center (lighthouse) and followed with the trees and sky. This allowed me to keep the top of the puzzle closer to me and push it away as I worked my way down to the sea. I found this reduced the time I usually spent standing, hunched over the puzzle. I am amazed it took me 40 years of jigsaws to figure this out.

3. The sea and rocks took way longer than I thought. It was brutal.

Yeah, so what do I do now? Maybe I will stick a note on the cover before sending it back to Goodwill

Yes! You Nailed it!!

So for common folk like myself, what do I need to do? I used Authy for a few sites. Can a bad actor pretending to be me now get access to those sites?

They already have, no?

2001: A Space Odyssey still holds up pretty well both technically and narratively.
