What type of permissions is typically optimal for service accounts that create API keys in Okta?

The most suitable type of permissions for service accounts that create API keys in Okta is Read-Only permissions. This is because Read-Only permissions allow the service account to access data without the ability to make changes to it, thus minimizing the risk of accidental or unauthorized modifications to critical settings and configurations within Okta.

Service accounts are often used to interact with the Okta API for tasks such as generating and managing API keys. By using Read-Only permissions, the service account can still perform necessary actions related to API key management, such as retrieving information to ensure proper functioning or monitoring without compromising the integrity of the overall environment. This practice aligns with the principle of least privilege, ensuring that accounts have only the permissions they need to perform their required tasks, which enhances security posture and reduces potential attack vectors.

Other permissions such as Full Administrative would grant excessive access, leading to increased security risks, while Custom and Limited may not specifically cater to the necessary actions required for managing API keys without overstepping boundaries. Thus, Read-Only is optimal for ensuring security while allowing essential functionality.
