Screenshots are common practice, but you often capture more than you need. Revealing too much of your screen in a single image can actually threaten your security. Instead, you can take a screenshot with precise cropping, so that you include only what you want.
On a Mac, press Command + Shift + 5, and a rectangle will emerge, which you can manipulate as much as you want.
On Windows 10, go to Start, enter the Search Bar, and type Snipping Tool. This will give you a similar box that you can drag to any shape over your screen.
