What is the password for the

I created a developer account: raulcejas04, raulcejas04@hotmail.com, raulcejas04@github.oktaidp

I am trying to authenticate using okta api: https://dev-85225556.okta.com/api/v1/authn, I don’t know my real username and password because I logged with github. Where can I get this values ? in dev account there is not a pasword option to change it.

I don’t find password option in the settings: My Apps Dashboard | okta-dev-85225556

Thank you.
