Account based system

[RealPortalPlayer]

A Username and Password system will make sure no one can act like someone else.
The problem about the username system is that if a youtuber uses this and recorded a video, someone could just copy that username and boom everyone will think hes the youtuber.

I agree

While I agree with this, it should only be implemented for people who join multiplayer servers. For people playing on LAN we shouldn't have to log in every time. Because in a LAN server everyone knows who the people on the server are. This login is a good idea for multiplayer servers only.

I think this is planned in the future. Although it's main purpose is to allow reliable banning & whitelists.

As @BPopcorn said authentication is planned in a future release with the main purpose of reliable cross server banning and whitelisting

This is a great idea, but please, make this optional. Not everyone needs this, and it would end up being an annoyance more often than not.
