Right now the answer would be sort-of. If you're a Wealthsimple Invest client as well as a Wealthsimple Trade user, then your login and security credentials will be the same for each profile. This being the case, if you have Two-Step Verification enabled through your Invest account, this will also be enabled for your Trade account.
That being said, if you are only a Wealthsimple Trade user (i.e. you do not have a Wealthsimple Invest account) we do not currently support standalone Two-Step Verification. Our team is working on this, so stay tuned!
