Sharing account information is disallowed, and permanently bannable, but the game doesn't allow you to enter your security codes privately. I'd like to request that this is changed in some way to make it more secure, as computer displays aren't always private. Editing this post in line with the valid comment below. Adaryn
You're quite possibly right. Surely it'd be better to have some other type of security such as 2FA on the account login instead of visually entering your unchanging security keys on the screen though?
