Unable to login after deleting Okta verify from Default Policy

Hi All,
I have created okta developer account and created a new application with OIDC- OpenId Connect and application type is web application and added people. When i try to login it was asking multifactor authentication with okta verify app, so i went to organizations default policy and deleted the okta verify from default policy from then i am not able to login to admin account itself to make any modifications. Suggest me how to login back or delete account and create new one.
