API Keys

An API Key consists of an access key and a secret key. API Keys authenticate with the Nessus REST API and pass with requests using the X-ApiKeys HTTP header.


  • Nessus only presents API Keys upon initial generation. Store API keys in a safe location.
  • Tenable Nessus cannot retrieve API Key. If you lose your API Key, you must generate a new API Key.
  • Regenerating an API Key immediately deauthorizes any applications currently using the key.
