My Lands: Black Gem Hunting

a friend of mine used to have an account. he left it and wants to give it to my brother (I want him to start playing too)

He is afraid the game will steal his email or something. is it possible to swap passwords for a player without the use of an email?
we got the acc name and a password.

It is necessary to change the e-mail and the password.
