need to access another user on my tablet login

[nixnutt800]

Galaxy Note 8.0: Son allowed a much older teen to setup a login on his tablet so that he could bypass parental locks. In doing so he created everything under a secret email account. I want to access the account to view exactly what they were up to, but cant guess the lock, and dont know the email address used. Is there any way to access those files, or reset the login info to see the details. Is there an app i can use to view those folders in the root drives? I know what I am asking to do, but Im trying to parent. Any help would be much appreciated

I would just ask your son to tell you the password. There really isn't a way to hack into it.
