What are the credential types supported by Jenkins?

Answer»

In Jenkins, credentials are a set of information used for authentication with internal/external services to accomplish an action. Jenkins credentials are PROVISIONED & managed by a built-in plugin called - Credentials Binding - plugin. Jenkins can handle different credentials as follows -

  • Secret text - A token such as an API token, JSON token, etc.
  • USERNAME and password - Basic Authentication can be stored as a credential as well.
  • Secret FILE - A secret file used to authenticate some secure data services & security handshakes.
  • SSH Username with a private key - An SSH public/private key pair for Machine to Machine authentication.
  • Certificate - a PKCS#12 certificate file and an optional password.
  • Docker Host Certificate Authentication credentials.

And as we can guess, this can be extended to several other extensible credential TYPES like - AWS credential, Azure secrets, etc. using commonly available plugins.
