Account creation is done through Special:CreateAccount. There are three types of account creation, each with a separate log event action type:

• create — a new user creates their own account.
• create2 — another user account is created by an existing user.
• autocreate (up until MediaWiki 1.26) — a new account is autocreated using AuthPlugin . AuthPlugin has been superseded by AuthManager .

It is possible, through the configuration setting $wgGroupPermissions , to disable account creation or to limit it to sysops; see Manuale:Impedire l'accesso (which describes how a sysop may create another user's account).
