A social media account shared by three staff members. A shared mailbox where the password has not changed in two years. A SaaS tool where everyone logs in as “admin” because setting up individual seats felt like a hassle.
These situations are far more common than most business owners realize, and they undermine even the strongest cybersecurity protections in place elsewhere.
As organizations adopt passwordless authentication, the assumption is often that shared credential risks go away. But they do not, they just shift.
The Problem with Shared Credentials
A shared credential is any login used by more than one person. The most common examples are social media accounts, shared inboxes, billing portals, or generic admin accounts on software platforms.
On the surface, sharing a login seems harmless. It avoids the cost of an extra seat or spares someone the effort of setting up individual access.
In practice, shared credentials destroy accountability. When five people use the same login, there is no way to know which one approved a payment, deleted a file, or sent a message. Audit logs become meaningless for investigation purposes.
According to the Verizon 2025 Data Breach Investigations Report, stolen or misused credentials were involved in 22% of breaches.
Why Passwordless Does Not Automatically Fix This
Moving to passwordless authentication using passkeys, biometrics, or hardware security keys is a meaningful security upgrade. It eliminates an entire category of attacks built around stealing, guessing, or reusing passwords. But shared credentials are a people-and-process problem, not a technology one.
A shared passkey or shared biometric enrolment still means multiple people are operating under the same identity. If a device enrolled to that account is compromised, the attacker gains the same level of access as a legitimate user.
The audit trail does not improve, and the offboarding challenge may become even more complicated. Revoking access for one departing employee can inadvertently affect others who rely on the same enrolment.
Passwordless authentication strengthens the login process, but it does not address the underlying risks created by shared accounts. As long as multiple people continue to use a single identity, the security and management challenges remain.
Shared Credentials and Canadian Compliance
For Canadian businesses, shared credentials carry a specific legal dimension.
PIPEDA (the Personal Information Protection and Electronic Documents Act) requires organizations to protect personal information using safeguards appropriate to its sensitivity. That includes controlling who has access and being able to account for how data was used.
When credentials are shared, an organization cannot demonstrate individual accountability. In the event of a breach or privacy complaint, the inability to produce a reliable access log is a significant compliance liability.
Industries with additional obligations such as healthcare under PHIPA, legal under LSO requirements, financial services under various federal guidelines face compounded exposure. Shared accounts often fail the access control audits these frameworks require.
Practical Steps to Reduce Shared Credential Risk
Eliminating shared credentials entirely is the goal, but it rarely happens overnight. A phased approach works well for most businesses.
1. Audit what is actually shared
Start by listing every platform where a shared login exists. Include social media, shared inboxes, vendor portals, and any software where staff use a generic account. This list is usually longer than expected.
2. Assign individual access where possible
Most modern SaaS platforms offer individual user seats. For platforms that do not, consider whether the tool is essential or whether it can be replaced with one that does support per-user access. Individual accounts mean individual audit trails and individual revocation on offboarding.
3. Use a privileged access or credential management tool
Where shared access is unavoidable, credential management tools allow access to a shared login without exposing the underlying password to any individual. Access can be granted and revoked without changing the credential itself, and the tool logs who accessed what and when.
4. Tighten offboarding procedures
Shared credentials frequently stay active long after an employee leaves, because changing the password disrupts everyone still using it. A documented offboarding checklist that includes reviewing and rotating shared credentials reduces this exposure significantly.
5. Connecting This to a Broader Security Strategy
Shared credentials are one piece of a larger identity management picture. If your organization is considering or already implementing passwordless authentication, reviewing credential sharing practices at the same time makes the transition more complete.
For context on how to build a practical passwordless approach for your team, the steps are similar: map current access, assign individual identities, and enforce through tools and process rather than trust.
It is also worth reviewing IT compliance requirements in your industry as part of this process. Many businesses discover that shared credentials represent an existing compliance gap that needs addressing before an audit or incident forces the issue.
The goal is not to make access harder. It is to make access traceable, revocable, and defensible.
Want Help Reviewing Your Access Controls?
Shared credentials create gaps that can be difficult to identify from the inside. A structured access review looks at who has access to what, flags shared logins and dormant accounts, and maps current practices against your compliance obligations.

Article FAQs
What counts as a shared credential?
Any login used by more than one person is a shared credential. Common examples include team social media accounts, shared billing portals, generic admin accounts, and any platform where a single username and password is distributed among several staff members.
Does going passwordless eliminate shared credential risks?
Not automatically. Passwordless authentication improves security by removing the vulnerability of passwords, but shared accounts still create accountability gaps, complicate offboarding, and reduce your ability to produce reliable audit logs. Individual identities are needed regardless of the authentication method used.
How does PIPEDA apply to shared credential use?
PIPEDA requires Canadian businesses to protect personal information with appropriate security safeguards, including access controls. Using shared credentials makes it impossible to demonstrate who accessed personal data and when. In a breach or privacy complaint, that lack of accountability is a compliance liability.
