Authorized keys are a pair of public and private keys that are used when creating a JSON Web Token. A JSON Web Token is required when requesting an IAM token for a service account.
A private key is returned when creating a new pair of keys, while a public key is contained in the Key resource.
The private key of a service account is the confidential information which allows you to perform operations in Yandex.Cloud. Keep your private key in a secure location.
