How to Login

Prerequisites

Logout from any existing npm sessions to avoid conflicts:

npm logout

Step 1: Generate a New npm Access Token

You must generate a new access token on the npm website with specific permissions.

1. Log in to your account on the npm website.
2. Navigate to Account Settings (your profile icon in the top right).
3. Select Access Tokens from the menu.
4. Click the "Generate New Token" button.
5. Configure the Token:
   • Token Type: Select "Publish". This grants the token the ability to publish new packages and versions.
   • Crucial Step: Ensure you check the box for "Bypass 2FA for publishing" (or a similarly worded option). This is the key requirement to resolve the E403 error without an OTP.
6. Click "Generate Token" and immediately copy the token that is displayed. You will not be able to view it again.

Step 2: Configure the Token in Your Environment

You need to tell the npm CLI to use this new token when communicating with the registry.

Option A: Local .npmrc File (Development)

Run the following command in your terminal, replacing <YOUR_NEW_TOKEN> with the token you copied in Step 1.

npm set //registry.npmjs.org/:_authToken <YOUR_NEW_TOKEN>
