Error signature — confirm this is yours before buying:
403 Forbidden - PUT https://registry.npmjs.org/... Two-factor authentication or granular access token with bypass 2fa enabled is required to publish packagesnpm ERR! code EOTPThis operation requires a one-time password from your authenticator.You can provide a one-time password by passing --otp=<code> to the command you ran.npm · publish · 2fa · tokens · documented
npm CLI reports EOTP when an interactive publish needs a current one-time password; non-interactive publishing can instead surface the registry's 403 requirement for 2FA or an authorized bypass path. Classic npm tokens were permanently revoked in December 2025, so older advice to create a Classic Automation token can no longer work.
Confirm the exact signature and listed technology tags before buying. The remediation and verification procedure remain paid.
