Security credentials are a pair of an access key and a secret key. You use the keys pair for AWS Signature v4 authentication.

Cloudian HyperStore supports user and application types of security credentials. You can use the keys pair to authenticate S3 API requests and to access and manage objects and buckets.

With S3 API requests, authenticated with user credentials, you can manage all objects that you own or the objects that are shared with you.

With application credentials, you control the S3 API access at the bucket level.

If you use AWS S3 or ECS, you can only use user credentials to authenticate S3 API requests. With AWS S3 and ECS, each user account has a single pair of an access and secret keys.

You can rotate the user credential. The rotation only updates the secret key. When you rotate a user credential, the old secret key remains active for five minutes.
