Logging in and out

Creating a user and Logging In

To publish a package, you must have a user on the npm registry. If you don't have one, you can create it 2 ways:

• On the npm website
• Using npm adduser

Note: If you created one on the site, use npm login to store the credentials on the client.

Once you have created a user and logged in, you can use npm config ls to ensure that the credentials are stored on your client. You can also check that your user has been added to the registry by going to https://npmjs.com/~username.

npm whoami

To see what username you are logged in as, you can enter:

npm whoami [--registry <registry>]

Logging Out

To log out, use the npm logout command:

npm logout [--registry=<url>] [--scope=<@scope>]

When logged into a registry that supports token-based authentication, this command will 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.

Configuration

You can configure the logout command 2 ways:
