What does the term shared account mean in Cyber Essentials?

A shared account is a single login that more than one person uses, such as one office email login whose password the whole team knows.

How does shared account apply to Cyber Essentials?

In plain terms

A shared account is like a whole team signing the visitor book with the same name. Nobody can tell who came in or when. When one person leaves, the password has to be changed and passed round to everyone else, which is easy to forget. Common examples are one "reception" login on a front desk PC, one login for the firewall, or one admin account used by everyone at an IT support company.

What Cyber Essentials asks

The NCSC requirements say your organisation must "authenticate users with unique credentials before granting access to applications or devices". A7.2 asks: "Are all your user and administrative accounts accessed by entering unique credentials?" The guidance is direct: "You must ensure that no devices, applications or cloud services can be accessed without entering unique access credentials. Accounts must not be shared."

This includes accounts used by suppliers. The requirements state that all accounts your organisation owns are in scope, even when a third party such as a managed service provider uses them.

Common mistakes

  • Treating a shared mailbox as a shared account. In Microsoft 365, people open a shared mailbox through their own login, so each person still has unique credentials.
  • One admin login for the router or firewall known by several people.
  • A generic login on a shop floor or warehouse PC. Each person needs their own account.
