Your account
The Account button in the top bar opens your account page; Escape or "Back to the game" closes it (Closing a pop-up).
It shows the email address you sign in with, and Sign out lives there too. The invite code you typed when you made the account is used once and is never needed again.
You can set your first name and surname, which the game uses to address you in its letters.
You can change your password: type it twice and save, using at least 6 characters.
Careful, saving a new password signs you out on every other device where you are signed in.
The page also holds the tip link (Supporting the game), the privacy policy, the terms, and the two big decisions: a new career and deleting your account.
