Perhaps even Mojang knows it's an alt account. ( I typed the version as 1.16.1 but, This problem does not matter the version )
Bad users who produce alt accounts hack into the ID and password of the game's account with only people's nicknames and his IPs.
Soon it was used for their illegal business and many people were harmed. Please don't allow me to use the alt account.
Thank you for your report!
