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.

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)

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.
