-description: Add a registry user account
----

-### Synopsis
-
-<!-- AUTOGENERATED USAGE DESCRIPTIONS -->
-
-### Description
-
-Create a new user in the specified registry, and save the credentials to the `.npmrc` file.
-If no registry is specified, the default registry will be used (see [`registry`](/using-npm/registry)).
-
-When you run `npm adduser`, the CLI automatically generates a legacy token of `publish` type.
-For more information, see [About legacy tokens](/about-access-tokens#about-legacy-tokens).
-
-When using `legacy` for your `auth-type`, the username, password, and email are read in from prompts.
