Unfortunately, there is no direct way to do simultaneous multiple accounts. Here is a workaround:

Use Chrome profiles. Go to the Chrome Settings page, go to section Users. Add a new user.

These "users" - when you create a new one, it's like fresh Chrome installation. No bookmarks, no history, no extensions. Each user has its own set of the mentioned items.

This is also advisable for your setup for a multi-user computer, so your history, bookmarks, extensions, etc are isolated from your nephew's.

So, how does this relate to KC3? Since each user profile has its own "Chrome" data set, a KC3 on your nephew's profile will not conflict with a KC3 on your profile. Both of you have separate history, bookmarks, and extension, as mentioned.

Good thing is, each user profile can be opened each on its own window. So you can just alt-tab between profiles.

Additionally, if the specific profile is logged-in on your Gmail. It will carry everything over when you sign-in to another computer. Bookmarks, History, so it automatically syncs between devices.

Research more about the subject and it really is convenient, not only for KC3 and gameplay.
