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: none
If specified, you will be logged out of the specified scope. See npm help 7 npm-scope.
