FOSS gamedev and creative worlds

As Title,I had follow posts and search from google,But still had no idea. I try to remove the "player" folder in the world folder,But it seems useless,player's password is still here,because of server have answer me "WRONG PASSWORD".

Is any idea about remove a play(for testing)? Thx All

The files in the player folder contain the position and inventory.
To remove the password and privs of a player you have to edit the auth.txt file in the world.

Or you can do
/revoke playername all
and
/setpassword playername some_random_password_they_will_not_guess

It works,Tks PilzAdam & CraigyDavi...
