Which level of permissions should be assigned to a service account that needs to create an API key without modifying configurations in Okta?

Assigning the Read-Only Administrator permissions to a service account that requires the ability to create an API key without modifying configurations in Okta is the appropriate choice. This permission level allows the user to access information within Okta but does not grant the ability to alter configurations or settings.

With Read-Only Administrator rights, the service account can still create API keys necessary for integration or automation tasks, as this action typically falls under accessing the API key management features without needing to modify broader account settings or security policies. This strikes a balance between giving the service account the necessary permissions for its function while maintaining a level of security by restricting configuration modification abilities.

Higher permission levels, such as Full Administrator or Super Administrator, would include capabilities that allow for configurations to be modified, which is beyond the needed scope of the task. Similarly, a Group Administrator usually focuses on managing group-related permissions and tasks, rather than API integrations or key creations. Thus, the Read-Only Administrator level best fits the requirement of creating an API key while avoiding access to modify the overall configurations within Okta.
