Effective management of New Relic license and user API keys is essential for maintaining security and operational efficiency, especially as organizations and their technical environments grow in complexity. The keys, which enable applications and scripts to communicate with New Relic, should be managed by understanding their various types, such as Ingest Keys for telemetry data, Browser Keys for monitoring, and User API Keys for authenticated API access. New Relic offers several tools for key management, including the New Relic UI for manual tasks, the NerdGraph UI for recurring operations with a GraphQL query builder, and the New Relic CLI for automating workflows. Key management best practices include regular key rotation, secure storage, auditing key activity, and applying the principle of least privilege to minimize security risks. These measures help secure data, streamline workflows, and reduce operational risks, aligning with an effective observability strategy.
