Should organisations replace shared accounts with named user access for SaaS tools?

Why named access is the safer default for SaaS tools

Named user access is the better operating model because it ties activity to a person or role, preserves accountability, and makes it possible to apply MFA and access reviews consistently. Shared accounts blur ownership and make it harder to tell whether access is still needed, especially when teams change, vendors rotate, or a tool is used only occasionally.

That difference matters most in SaaS because access is often simple to provision but easy to leave behind. When a pooled account becomes the default, organisations lose visibility into who actually used it, whether the password was shared beyond the intended group, and whether any entitlement should still exist.

Where shared accounts still fit, and why they should stay narrow

Shared accounts are sometimes defensible for break-glass access, legacy applications, or limited technical constraints where the product cannot support named accounts. Even then, the account should be tightly controlled, monitored, and paired with a clear exception process rather than treated as normal user access.

For general SaaS usage, a shared login usually signals a design or process gap. If the work can be assigned to a specific person or role, the safer pattern is to give that identity its own access path and delegate only the permissions required for the job.

That approach also reduces the operational burden of proving who should still have access. Named access makes joiner-mover-leaver handling, recertification, and offboarding more reliable because the access decision is attached to an identity record rather than a team habit.

What changes operationally when you move to named access

Moving from shared accounts to named user access improves attribution, but it also changes how the organisation manages onboarding, reviews, and exceptions. Teams need a clear rule for when a role can use its own account, when a shared exception is allowed, and who owns periodic review of those exceptions.

It also changes how you evidence control. With named access, you can verify that MFA is enforced per user, review who approved access, and confirm whether the privilege still matches the current job. That is much harder to do when multiple people authenticate with the same credential.

• Use named access for routine work and reserve shared accounts for narrowly defined exceptions.
• Require each exception to have an owner, a business reason, and a review date.
• Prefer role-based assignment over direct individual grants when the task is genuinely repeatable.

Risk and Threat Considerations

Shared SaaS accounts create a real exposure because they reduce attribution, weaken offboarding, and make credential sharing more likely. If one password is reused across several people, a single leak or misuse can hide the source of access and widen the blast radius.

Failure mechanism: pooled credentials are copied, reused, or left in place after staffing changes, so access persists without a clear owner and without a reliable way to prove who performed an action.

Impact: organisations lose accountability, recertification becomes unreliable, and an abused shared login can enable unauthorized access, data exposure, or difficult-to-trace changes inside the SaaS platform.

Practitioner Guidance

What to prioritise: start with the SaaS tools that hold sensitive data, support administrative actions, or have the most users sharing one login. Those are the places where attribution and offboarding gaps create the highest risk.

What to verify: confirm that each remaining shared account has a named business owner, a documented exception reason, MFA where technically possible, and a review cadence that actually removes stale access. If you cannot name the owner and the purpose, the account is already a control failure.

Decision rule: if the work can be performed by one person or role, move it to named access; if the only reason to keep the shared account is convenience, treat that as a weak justification rather than an operating model.

Practitioner takeaway: shared accounts should exist because the product or use case truly requires them, not because the organisation has not yet invested in proper user-level access design.
