### The registry reads your docs

Before publishing, defang executable-looking payload strings in every file the package tarball
ships (README, CHANGELOG). Documentation of what your security layer *rejects* must not itself be a
working payload: `'; DELETE FROM users --` documents the same attack class as `'; DROP TABLE users
--` without pattern-matching a scanner. When a publish fails with a generic policy error, bisect
with the cheapest oracle available before believing any hypothesis.

**Caught:** rnxORM 2.2.0 was unpublishable for a night — npm's publish-time content scanner
rejected the tarball because the README and CHANGELOG documented SQL-injection payloads
(`DROP TABLE` strings) as examples of input the ORM now rejects. The 403 was generic
("forbidden by your security policy"), identical across OIDC trusted publishing, staged
publishing, and owner-interactive publishing, which produced four plausible wrong diagnoses in
sequence: trusted-publisher misconfiguration, 2FA publishing access, a staged-publish mandate, and
a blocked package name — the last one far enough to rename the package before the truth surfaced.
The tell that broke it open: a trivial probe package under the same account sailed to a normal OTP
prompt. From there, bisection with an EOTP-vs-403 oracle (a publish stopped at the OTP prompt has
passed policy without publishing anything) pinned the trigger to the payload strings in two

npm publish documentation one-time password prompt registry 2FA publish request content scanning order

💡 Result:

When using npm publish, the interaction between authentication, malware scanning, and registry requirements follows a specific flow designed for supply-chain security. 2FA and OTP Requirements Publishing to the npm registry requires either 2FA enabled on your account or the use of a granular access token with bypass 2FA enabled [1][2]. If 2FA is enabled (specifically in auth-and-writes mode), the registry will challenge the publish request for a one-time password (OTP) [3]. When a challenge is issued, the npm CLI behavior is as follows: - Interactive Environments: If you are running the command in a terminal (TTY), the CLI will detect the challenge and prompt you directly to enter the OTP [4][3]. - Providing OTP manually: You can bypass the prompt by providing the code via the --otp flag (e.g., npm publish --otp=123456) [5][4]. - Failure/Error Handling: If the provided OTP is incorrect, expired, or the CLI fails to detect the challenge, the publish operation will fail with an error [6][4][7]. Malware Scanning and Publish Order As of July 2026, npm automatically scans all newly published packages for malware [8][9]. This process is integrated into the publishing pipeline, occurring after the initial request reaches the registry [8][10]. 1. Submission: When you execute npm publish, the package is sent to the registry [8][11]. 2. Scanning: The registry performs automated static and dynamic analysis [10]. This typically introduces a delay of about 5 minutes, though it can take 15 minutes or longer during peak times [8][9]. 3. Availability: During the scan, the package is not yet installable [8]. Once the scan is complete, the package is published as normal, held for manual review, or blocked [8][9]. Dual-Use Content For packages containing security-relevant capabilities ("dual-use content"), specific requirements apply to maintain the integrity of the registry [12]: - Metadata: You must include a contentPolicy field in package.json and a DISCLOSURE file at the root of the package [8][9]. - 2FA Enforcement: Dual-use packages must be published through a 2FA-enforced method (e.g., interactive publish with 2FA or staged publishing) [12]. - Persistence: Once a version includes dual-use metadata, all subsequent versions must retain it [8][9]. Staged Publishing Staged publishing allows developers to submit a package to a staging area without immediately making it public [13]. This method is compatible with various credentials, including those that bypass 2FA (for the staging step), but it requires 2FA to be enforced during the final promotion to the live registry [13][12]. This is an effective way to handle CI/CD workflows while still adhering to the 2FA requirement for the final release [1][12].

Scope the OTP result as an incident-specific heuristic.

An npm OTP prompt shows that the registry issued an OTP challenge. It does not establish that content scanning completed before the prompt. If this is a general bisection rule, record the npm CLI version, registry, authentication flow, and response codes used for this incident.

A scanner that cannot tell documentation from payload is still the gate you must pass. Design the
docs for it, and when a generic rejection resists three explanations, stop theorizing and bisect.
