Troubleshooting Zowe CLI credentials

Secure credentials

Authentication mechanisms

You can troubleshoot a failed log-in to a mainframe service by reviewing the authentication mechanisms used by Zowe CLI.

Zowe CLI accepts various methods, or mechanisms, of authentication when communicating with the mainframe, and the method that the CLI ultimately follows is based on the service it is communicating with.

However, some services can accept multiple methods of authentication. When multiple methods are provided (in a profile or command) for a service, the CLI follows an order of precedence to determine which method to apply.

To find the authentication methods used for different services and their order of precedence, see the table in Authentication mechanisms.
