Authenticate to a ServiceNow instance and store user credentials for accessing the instance on your system with the ServiceNow SDK.

After installing the ServiceNow SDK, you can authenticate to an instance with the ServiceNow SDK command-line interface (CLI) to begin developing applications and installing them on your instance. A non-production instance should be used for application development.

You can use basic or OAuth 2.0 credentials to authenticate to an instance. To use OAuth 2.0 authentication, you must first configure the instance to support OAuth 2.0 authentication with the ServiceNow SDK by installing the ServiceNow IDE (version 1.1 or later) or importing the required XML configuration.
