npm logout [--registry=<url>] [--scope=<@scope>]
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: https://registry\.npmjs\.org/
The base URL of the npm package registry\. If scope is also specified, it takes precedence\.
Default: The scope of your current project, if any, otherwise none\.
If specified, you will be logged out of the specified scope\. See npm help scope\|\.
