I would like to know if my oculus quest two has a warranty

Depends on when you bought it from Meta and how long you own. In most cases it is a 1 year warranty though in some countries it's 2 years due to local laws. Even then, depending on how it got broken it might not be covered. 

Hi Jasek4236​ 🙂

What Maccyb123​ said, even if your headset is still under warranty doesn't automatically mean everything is covered.

You can see the expire date of your warranty - or if it is already expired - on the following page.
