Who I have the same questioned this topic

Ok, so my girlfriend's son was fiddling around with his Pixel's passwords and forgot what he changed his password to. I read somewhere that the Pixel can't be reset if you don't know the password. Is this true? Or can I do the ol' power button/volume button factory reset?

I'm not home right now so just doing a bit of research before I get outta work. I got some laziness to get to when I get home and I don't wanna be spending a lot of time on it. Not to mention, I have to put screen protectors on both boys phones, too, and I HATE doing that.

Any help is appreciated!
