TL;DR: Shared user accounts remain common because they reduce licensing friction and simplify access, but they also destroy attribution, complicate offboarding, and expand the blast radius of compromise, according to Unixi. The security case for unique identities is no longer theoretical: shared access survives because governance is slower than operations.
NHIMG editorial — based on content published by Unixi: Shared user accounts and the security risks they introduce
By the numbers:
- NHIs outnumber human identities by 25x to 50x in modern enterprises.
- Only 20% have formal processes for offboarding and revoking API keys, and even fewer have procedures for rotating them.
- 97% of NHIs carry excessive privileges, increasing unauthorised access and broadening the attack surface.
Questions worth separating out
Q: What breaks when teams rely on shared accounts for privileged access?
A: Shared accounts break accountability first.
Q: Why do shared credentials create lasting security risk even when passwords are strong?
A: Strong passwords do not solve the governance problem created by shared access, unmanaged accounts, and credentials that survive after they are no longer needed.
Q: How do security teams know if service account governance is actually working?
A: Governance is working when every service account has an owner, a workload, a retirement condition, and an auditable rotation path.
Practitioner guidance
- Inventory every shared account and assign a named owner Build a current register of all shared logins, the systems they access, the users who rely on them, and the business reason each exists.
- Tie revocation to offboarding and role change events Define a mandatory rotation trigger when any person with access leaves, changes role, or no longer needs the account.
- Add attribution signals to shared-session logging Capture the user group, source location, device context, and timestamp for each shared-account session so investigators can reconstruct likely operator identity.
What's in the full article
Unixi's full article covers the operational detail this post intentionally leaves for the source:
- Why shared admin logins persist in legacy apps, appliances, and vendor portals.
- How Unixi's SSO flow preserves attribution when multiple users access a shared account.
- What the vendor says about MFA, step-up prompts, and deprovisioning through the IdP.
- The specific logging fields used to reconstruct who accessed a shared session.

Shared accounts: what governance gap are IAM teams overlooking?

Shared accounts are an accountability failure, not just a convenience trade-off. Once a single login represents several people, the organisation loses the ability to assign action to actor with confidence. That breaks the core identity governance premise behind audits, investigations, and privilege review. The implication is that shared access should be treated as a structural exception, not a normal operating model.
A few things that frame the scale:
- Only 20% have formal processes for offboarding and revoking API keys, and even fewer have procedures for rotating them, according to Ultimate Guide to NHIs.
- 79% of organisations have experienced secrets leaks, with 77% of these incidents resulting in tangible damage.
A question worth separating out:
Q: Who should be accountable when shared account access is misused?
A: Accountability should sit with the entitlement owner who approves access, maintains the account policy, and can remove users when needed. If no one owns those decisions, enforcement becomes inconsistent and users will continue to bypass controls through informal sharing or recovery workarounds.
