How do I get into the Slytherin common room on Pottermore if I'm not a Slytherin?

Hmm.. well, did u try the Polyjuice potion yet? If u did, then u might be able to get into the common room door going through the chapter, like u always do.. (I haven't been on Pottermore in forever so sorry if I get stuff wrong) If u can't do that, then maybe , try and add somebody that's a Slytherin and see if u can get in then. =/

I don't know perfectly but I've heard that u have to make the Polyjuice Potion........
