Default or documentation-provided secrets that are intended for examples, testing or setup. When they remain in production, they become real access material because systems and users may continue to trust them as if they were unique and approved.
Expanded Definition
Sample credentials are placeholder secrets that appear in documentation, tutorials, lab images, or onboarding guides to show how authentication should be configured. They are meant to be illustrative, not trusted for real access. The security problem begins when those examples are copied into live environments, reused by operators during setup, or left active after deployment. At that point, they stop being harmless demonstrations and become standing access material that attackers can discover through source code, container images, configuration files, or public repositories.
Within identity security, sample credentials sit at the boundary between documentation hygiene and operational control. They are not a formal identity assurance concept, but they can directly undermine the assumptions behind authentication, secret handling, and privilege boundaries. Standards such as NIST SP 800-63 Digital Identity Guidelines emphasise that authenticators and their use must support trustworthy identity assertions, which sample secrets can quietly erode if they are treated as acceptable beyond testing.
The most common misapplication is leaving example passwords, API keys, or tokens in production configuration after a pilot or migration, which occurs when teams treat documentation values as temporary but never replace them with unique secrets.
Examples and Use Cases
Implementing sample credentials rigorously often introduces setup friction, requiring organisations to balance ease of onboarding against the cost of making every environment use unique secrets from the start.
- A development team ships a container image with a default admin password shown in the README, and the password is never rotated after deployment.
- An internal API tutorial uses a fixed token to demonstrate calls, but the token is later accepted by a staging gateway that was cloned into production.
- A cloud workload inherits example access keys from a bootstrap script, creating a secret that security scanners can find and attackers can abuse.
- A partner integration guide includes a shared test credential, and the same value is copied into multiple tenants, defeating isolation.
- A non-human identity onboarding workflow references placeholder secrets in a template, but the placeholders are treated as live values once automation runs. This is exactly the kind of governance gap highlighted in the OWASP Non-Human Identity Top 10 when secret lifecycle controls are weak.
In practice, sample credentials are often created for speed, but they should be replaced with generated, unique, environment-specific secrets before any system reaches shared testing or production use.
Why It Matters for Security Teams
Sample credentials matter because they create a false sense of safety: teams may believe a secret is harmless because it was originally meant for examples, while attackers see a valid path to access. This is especially dangerous in environments that use automation, CI/CD pipelines, or non-human identities, where a single copied credential can spread across services and tenants. Good secret governance therefore depends on detection, rotation, and strict separation between demonstration material and operational secrets. Controls in NIST SP 800-53 Rev 5 Security and Privacy Controls are relevant here because they support configuration management, access control, and secret protection practices that reduce accidental reuse.
For security teams, the practical issue is not whether a sample credential was once intended for testing, but whether it still exists in any place where trust is enforced. Once that happens, the organisation may be exposing systems through a value nobody considered sensitive anymore. Organisations typically encounter account compromise, unexpected service access, or secret-scanning alerts only after an outage, code leak, or incident review, at which point sample credentials become operationally unavoidable to address.
