Split-screen allows players to impersonate others on Realms and servers

ASE - Account Smuggle Exposit

 

So when your on a console, you can split screen. However you cant do this on multiplayer servers. That being said, if you had an account that could join a realm, then split screen to add another account, the account will join regardless if it has been invited from the realm.

 

! THE FOLLOWING HAS ONLY BEEN TESTED ON NINTENDO SWITCH !

On the Nintendo Switch you can make user profiles. You can name these anything with a max of 10 characters. When preforming ASE, the account being smuggled into the realm will have the username of the profile that it is under. This effectively lets you impersonate anyone who has a 10 or less character name on a realm provided that you have an actual account that can join the realm.

 

! VIDEO INFO !

The video is as 2x speed and was cut when the 2nd account was loading in because it took a minute to load in and a few seconds to join the realm
