PT activity password is set by owner or creator of that particular activity. This password prevents using shortcuts and cheating and make sure that you follow the lab . If you did not create PT activity lab, you cannot change anything inside PT activity lab. Unfortunately, there is nothing that prevents students from sharing work/solutions 100%. In last 30 days or so, I have seen the same PT file from different users 3 times fishing for answers.
if you are trainer, you should have access to solutions as well.
