npm-adduser — Add a registry user account
npm adduser [--registry=url] [--scope=@orgname] [--always-auth] aliases: login, add-user
Create or verify a user named <username> in the specified registry, and save the credentials to the .npmrc file. If no registry is specified, the default registry will be used (see npm help 7 npm-config).
The username, password, and email are read in from prompts.
To reset your password, go to https://www.npmjs.com/forgot
To change your email address, go to https://www.npmjs.com/email-edit
You may use this command multiple times with the same user account to authorize on a new machine. When authenticating on a new machine, the username, password and email address must all match with your existing record.
npm login is an alias to adduser and behaves exactly the same way.
The base URL of the npm package registry. If scope is also specified, this registry will only be used for packages with that scope. See npm help 7 npm-scope.
If specified, the user and login credentials given will be associated with the specified scope. See npm help 7 npm-scope. You can use both at the same time, e.g.
npm adduser --registry=http://myregistry.example.com --scope=@myco
This will set a registry for the given scope and login or create a user for that registry at the same time.
If specified, save configuration indicating that all requests to the given registry should include authorization information. Useful for private registries. Can be used with --registry and / or --scope, e.g.
npm adduser --registry=http://private-registry.example.com --always-auth
This will ensure that all requests to that registry (including for tarballs) include an authorization header. This setting may be necessary for use with private registries where metadata and package tarballs are stored on hosts with different hostnames. See always-auth in npm help 7 npm-config for more details on always-auth. Registry-specific configuration of always-auth takes precedence over any global configuration.
