If you have a paid user account, but no longer need private packages, you can downgrade your paid organization to a free organization. When you downgrade from a paid to a free organization, you will lose the ability to install and publish private packages at the end of your last paid billing cycle. Your private packages will not be made publicly visible when you downgrade to a free plan.

1. On the npm "Sign In" page, enter your account details and click Sign In.
2. In the upper right corner of the page, click your profile picture, then select Billing Info.
3. Under "change plan", click Downgrade Plan.
4. Under "Are you sure?", click Downgrade to a free account.
