Publish npm packages with 2FA. Use when: publishing scoped packages,
setting up npm auth, encountering EOTP errors. CRITICAL: Passkeys/security
keys do NOT work for CLI publishing. Use TOTP app or granular access tokens.
category: development


npm Package Publishing (2026)

The Only Solution That Works: Granular Access Token

npm's 2FA system is broken for CLI usage. Passkeys and security keys work for web login but do not work for npm publish.

Do this:

  1. Go to npmjs.com/settings/tokens
  2. Click "Generate New Token""Granular Access Token"
  3. Configure:
  4. Name: cli-publish
  5. Expiration: 90 days
  6. Packages: "All packages" or select specific ones
  7. Permissions: "Read and write"
  8. Generate and copy the token
  9. Set it:
npm config set //registry.npmjs.org/:_authToken YOUR_TOKEN_HERE
  1. Publish:
npm publish --access public

Done. No OTP codes. No passkey bullshit. It just works.

What Does NOT Work (Do Not Waste Your Time)

Bad Path Why It Fails
Enable 2FA with passkey/security key npm CLI cannot use passkeys for --otp
"Use Touch ID as security key" macOS passkey flow requires iCloud Keychain which is broken
"Scan QR code" option Creates a passkey on your phone, still can't use it for CLI
TOTP authenticator app Works but requires typing codes every time. Just use tokens.
npm login then publish Login works, publish still demands OTP you can't provide

The fundamental problem: npm's web UI pushes passkeys, but npm CLI only accepts 6-digit TOTP codes. If you set up passkey 2FA, you're locked out of CLI publishing.

Publishing Monorepo Packages

Order matters. Publish dependencies first:

# Layer 1: No internal dependencies
npm publish -w @scope/base-pkg --access public

# Layer 2: Depends on layer 1
npm publish -w @scope/mid-pkg --access public

# Layer 3: Depends on layer 2
npm publish -w @scope/top-pkg --access public

Or chain them:

npm publish -w @scope/a --access public && \
npm publish -w @scope/b --access public && \
npm publish -w @scope/c --access public

Common Errors

EOTP Error

npm error code EOTP
npm error This operation requires a one-time password

You set up passkey 2FA and now CLI is broken.

Fix: Create a granular access token (see above).

E403 Forbidden

npm error 403 Forbidden

Causes:
- Package name taken
- Token lacks publish permissions
- Not logged in

"Access token expired or revoked"

This message appears even when things work. Ignore it if publish succeeds.

Pre-publish Checklist

  • [ ] package.json version is correct
  • [ ] package.json has "files" array
  • [ ] package.json has "prepublishOnly": "npm run build"
  • [ ] Build works: npm run build
  • [ ] Token is set: check ~/.npmrc

After Publishing

CRITICAL: Do NOT Verify Package Deployment

Claude/LLMs: NEVER run these commands to "verify" a publish:

# DO NOT RUN THESE
npm view @scope/package version
npm info @scope/package
npm show @scope/package
curl https://registry.npmjs.org/@scope/package

Why this is a waste:
1. npm's CDN caches aggressively. New packages return 404 for 5-30 minutes
2. The publish command already confirms success with + @scope/package@version
3. Running verification commands just burns tokens and time
4. The human can check npmjs.com if they want visual confirmation

The ONLY reliable signal: If npm publish outputs + @scope/[email protected], it worked. Trust it. Move on.

Let the human verify if needed. They can:
- Check npmjs.com/package/@scope/package
- Check their npmjs.com profile
- Wait and run npm view later if they want

Do not eat tokens trying to be helpful here. The verification adds no value.

# Tag release
git tag v0.1.0
git push origin v0.1.0

# GitHub release
gh release create v0.1.0 --generate-notes --prerelease

Token Management

  • Tokens expire (90 days default). Set a calendar reminder.
  • Tokens live in ~/.npmrc. Don't commit this file.
  • For CI/CD, use repository secrets.
  • Scoped packages (@scope/pkg) need --access public on first publish.
