Add a registry user account
npm adduser [--registry=url] [--scope=@orgname] [--always-auth]
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-config(7)).
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.
Default: http://registry.npmjs.org/
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-scope(7).
Default: none
If specified, the user and login credentials given will be associated
with the specified scope. See npm-scope(7). 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.
Default: false
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. See always-auth in npm-config(7) for more
details on always-auth. Registry-specific configuration of always-auth takes
precedence over any global configuration.
