Log out of the registry
npm logout [--registry=url] [--scope=@orgname]
When logged into a registry that supports token-based authentication, tell the server to end this token's session. This will invalidate the token everywhere you're using it, not just for the current environment.
When logged into a legacy registry that uses username and password authentication, this will clear the credentials in your user configuration. In this case, it will only affect the current environment.
If --scope is provided, this will find the credentials for the registry
connected to that scope, if set.
Default: http://registry.npmjs.org/
The base URL of the npm package registry. If scope is also specified,
it takes precedence.
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.
