Creating key pair for OCI REST API

Summary:

Hello.
I would like to know how you decided on the method for generating the key pair used to execute OCI's REST API.The documentation mentions both generating the key pair in the OCI Console and generating it locally.
I would be happy to hear examples from people who are actually using the private key about which method they chose and why they chose that method.
Any response will be welcomed. Thank you.
