A Vultr account Application Programming Interface (API) key authenticates requests to the Vultr API. You should regenerate the Vultr account API key periodically to reduce the risk of unauthorized access or if you suspect an authorized person has access to the key.
Follow this guide to regenerate API keys for users using the Vultr Customer Portal.
Navigate to Account and select Users under OTHER.
Select the user from the list and click the Edit User icon.
Click the Generate new API key icon to generate a new key under the User API Key section.
