Canonical account


A canonical account, in the context of computer software and systems, is an account that is included by default with a program or firmware. Such accounts usually also have a default password and may have certain access rights by default.
As such accounts and their password and permissions are usually common knowledge, given that anyone possessing a copy of the software, the device or their documentation will likely know of the account, a common security measure is to change the account's password and to double-check or modify the groups it is included in, or simply disable or delete it if it is not required.
