Key Highlights
- Shared admin accounts are rarely the result of carelessness - they accumulate through reasonable operational decisions, then quietly remove individual accountability
- The control auditors are really testing is attribution: can a privileged action be tied to a named, authorised individual at a specific time?
- Documentation and MFA prove an account exists and is protected at login, but neither proves who performed an action afterwards
- Knowing who your admins are is not the same as being able to evidence what a specific person did
- NIS2, DORA and ISO 27001 increasingly expect privileged actions to be attributable and supported by evidence, not simply documented
- The better question is not "do we have shared accounts?" but "can we attribute every privileged action to a named individual and produce reliable evidence on demand?"
What this means:
A shared admin account is a privileged account used by more than one person to perform administrative actions. The audit risk is that logs may show what the account did, but not which named individual performed the action, whether they were authorised at that moment, or whether reliable evidence exists to prove it. Shared administrator accounts are usually a symptom, not the root cause. The underlying issue is attribution: privileged access has grown faster than the governance needed to connect each action to an accountable individual and evidence it on demand.
What is a shared admin account?
The audit appears to be going well. Your access control policy is documented, multi-factor authentication is in place, privileged accounts are inventoried, and access requests follow an approval process. Then the auditor points to a single administrator login used by three members of your infrastructure team and asks a deceptively simple question:
"Last Tuesday, this account made a change to a production system. Can you show me which individual was responsible?"
There is a pause. Everyone in the room knows it was probably one of three people. Nobody can prove which one. In that pause, a control that seemed operationally practical yesterday becomes an audit finding today because it cannot establish individual accountability.
Shared administrator accounts are a common issue auditors flag, and one of the most commonly misunderstood. They rarely exist because anyone was careless. They exist because, at some point, sharing a credential was the fastest way to keep systems running, or because default and built-in administrator accounts were created as part of the system design or installation. This article looks at why that practical decision can quietly become a security, compliance, and operational risk, and what the question behind the audit finding is really testing: whether the organisation can reliably connect privileged activity to a specific, accountable individual.
Why do shared admin accounts happen in the first place?
It is important to be candid about why shared accounts persist. The common view that they are simply poor practice overlooks how reasonable operational decisions can create long-term identity risk.
Privileged access often grows organically. An admin credential is created to deploy a system, then reused by the project team to meet a deadline. A break-glass account is established for emergencies, then gradually becomes part of normal operations. A service account is configured once, while its password remains in a shared vault, a configuration file, or institutional memory. A senior engineer changes role but keeps access "just in case".
On the surface, nothing appears broken. Systems run, teams deliver, and shared access feels efficient. The risk is not only that the account exists, but that it removes individual accountability, weakens access governance, and makes misuse or compromise harder to detect.
What's the real problem with a shared account?
When a single credential is used by several people, accountability breaks down. Logs may show that the account made a change, but they cannot reliably show which individual performed the action. For privileged access, that gap creates a serious audit and risk issue because activity becomes difficult to attribute to a named, authorised person.
This is why shared privileged accounts are scrutinised so consistently during audits. Auditors are not only reviewing the account itself. They are assessing whether the organisation can answer three essential questions for any privileged action:
- Who performed the action as a named individual?
- Were they authorised to perform it at that specific time?
- Can the organisation produce reliable evidence without reconstructing it after the fact?
A shared admin account makes all three questions harder to answer. Because privileged accounts can bypass controls, access sensitive data, and make broad system changes, weak accountability in this area draws particular attention from auditors and regulators. Where risk is concentrated, control expectations are higher, and privileged access is often where those expectations are tested first.
Which assumptions are worth re-examining?
Many teams that rely on shared accounts operate under assumptions that seem reasonable until they are tested.
"It's fine because the account is documented and protected by MFA."
Documentation and multi-factor authentication help show that the account exists, is known, and requires an additional verification step before access is granted. But they do not reliably prove which individual performed a specific action after login. These controls strengthen access protection, but they do not create individual accountability. An auditor may recognise the presence of documentation and MFA while still identifying a control gap if actions cannot be traced to a named person.
"We know who our admins are."
Knowing who has administrative privileges is not the same as being able to attribute a specific action to a specific individual at a specific time. A list of authorised users provides visibility into access rights, but it does not govern or evidence actual activity. That distinction may seem minor until an incident occurs and the organisation must answer questions with records, not assumptions.
"It's just an audit finding."
The audit finding is only the visible symptom. The underlying issue is an operational and investigative gap. If a shared account is involved in a security incident, the same lack of attribution that concerns the auditor also affects the investigation. Was the access legitimate? Was it monitored? Who approved it? If those answers are unclear, regulatory, reputational, and operational exposure can increase quickly - not necessarily because of negligence, but because the account structure did not support defensible answers.
Why is this harder to ignore than it used to be?
Regulatory expectations are moving beyond documenting controls to proving that they operate effectively and consistently. For regulated organisations in Europe, accountability for privileged activity is now a board-level risk issue, not only a technical control.
NIS2 requires appropriate cybersecurity risk-management measures, including access control, authentication, and credential management, while making management bodies responsible for approving and overseeing those measures.
DORA's ICT risk-management rules for financial entities require identity management, unique identification and authentication, access-rights governance, and periodic review of access rights.
ISO 27001 similarly reinforces the need for controlled access, traceable user activity, and accountability within an organisation's information security management system.
The common implication is clear: privileged actions should be attributable to a responsible individual and supported by evidence. Shared administrator accounts weaken that position because they obscure who performed a privileged action, even when the account itself is documented.
What's the better question to be asking?
When organisations recognise this risk, the first instinct is often to remove shared accounts one by one. That work is important, but it addresses only part of the problem. Shared accounts are usually a symptom of a broader issue: privileged access has expanded faster than the governance needed to control, monitor, and evidence it.
A more valuable question is not simply, "Do we have shared accounts?" It is:
"Can we attribute every privileged action to a named individual and produce reliable evidence across all critical systems when required?"
Organisations that can answer yes typically have several practices in place. Privileged identities are inventoried, assigned to accountable owners, and reviewed regularly. Standing shared access is minimised in favour of named, controlled access. Privileged sessions can be monitored, recorded where appropriate, and reviewed based on risk. Audit evidence is generated through normal access processes rather than assembled manually under time pressure before an audit.
Achieving this requires more than deploying a tool. It requires treating privileged access as a continuously governed risk area. The shared administrator account is often the most visible sign of whether that discipline is in place.
Concerned about shared privileged access?
If you cannot confidently attribute privileged actions to named individuals across critical systems, the issue may go beyond a single shared account. A PAM Quick Check helps identify where privileged access controls, evidence and ownership need to improve. Book your PAM Quick Check.

If the audit question at the top of this page felt uncomfortably familiar, the shared account is unlikely to be the whole story - it is usually the first thread you pull.
