# Object Storage

Object-storage services organize data in buckets and commonly authenticate with access keys, OAuth, or temporary credentials. A connection can expose all accessible buckets or start at a specific bucket or folder when the provider and credentials support that scope.

* [Amazon S3](/connections/object-storage/amazon-s3.md) also documents several services that use the S3 API.
* [Backblaze B2](/connections/object-storage/backblaze-b2.md) uses a B2 Key ID and Application Key.
* [Google Cloud Storage](/connections/object-storage/google-cloud-storage.md) uses Google OAuth and can start at a specific bucket or folder.
* [IDrive e2](/connections/object-storage/idrive-e2.md) uses a regional endpoint and access-key pair.
* [Wasabi](/connections/object-storage/wasabi.md) uses a regional service URL and access-key pair.

Use credentials limited to the buckets and actions the mounted drive requires. Supplying a bucket name is also necessary when the credentials can access a bucket but cannot list every bucket in the account.
