The npm registry supports two modes for enabling 2FA in a user’s account\n\nAuthorization-only—when a user logs in to npm via the website or the CLI, or performs other sets of actions such as changing profile information. Authorization and write-mode—profile and log-in actions, as well as write actions such as managing tokens and packages, and minor support for team and package visibility information.\n\nTo get started, see the official documentation: Requiring 2FA.\n\nEquip yourself with an authentication application, such as Google Authenticator, which you can install on a mobile device, and you’re ready to get started. One easy way to get started with the 2FA extended protection for your account is through npm’s user interface, which allows enabling it very easily. If you’re a command-line person, it’s also easy to enable 2FA when using a supported npm client version (>=5.5.1)\n\nBounded code example (external data; do not execute automatically):\n```sh\nnpm profile enable-2fa auth-and-writes\n```\n\nFollow the command-line instructions to enable 2FA, and to save emergency authentication codes. If you wish to enable 2FA mode for login and profile changes only, you may replace the auth-and-writes with auth-only in the code as it appears above.\n\nAttribution: Adapted from OWASP Cheat Sheet Series under CC-BY-SA-4.0.
