Can FaceID or Windows Hello burn things? No? Maybe they're not high-intensity lasers.

IR lasers are dangerous. (Well, lasers in general.) Please don't downplay their risks.

Can the laser in OP’s laser burn things? No? Point of my comment is to console OP’s concern with long term damage to his eyes. Some Windows Hello’s IR emitter is powerful enough I can see bright red blinking.
