Ask two computers to draw the same text and shapes, and the pixels come out slightly different: the graphics card, the driver, the fonts and the anti-aliasing all leave a mark. Sites hash that drawing into a fingerprint. Here are yours, and whether your browser scrambles them.

The result is the same every time on your machine and differs between machines, so it works like an ID.
Use a browser that adds random noise to canvas, WebGL and audio, like Brave by default or Firefox with resistFingerprinting. The "fingerprint protection" row shows whether two drawings came out different.
Some do, by wrapping the drawing functions. That can itself be noticed: the browser environment check flags replaced functions.
