How to share Amazon S3 bucket with another AWS user

Please check out this manual if you would like to create sub-accounts under your main AWS account and grant them permissions to your bucket

How to edit bucket/file permissions

Please check these articles to learn the basics of Permissions editing. Here we will explain some additional features of the Permissions editor.

Permisions Table - Rows

Each row represents Grantee. There are four types of Grantees:

  • Owner
  • Authenticated Users
  • All Users
  • User by Email/Id

Owner - Every bucket/file in Amazon S3 has an owner, the user that created the bucket/file. The owner of a bucket/file cannot be changed.

Authenticated Users - Anyone with an Amazon AWS account. Although this is inherently insecure as any AWS user who is aware of the bucket/file will be able to access it, you might find this authentication method useful.

All Users - Anonymous access to any Amazon S3 bucket or file. Any user will be able to access the files.

User by Email/ID - User with Amazon Web Services account. You use Email or ID to specify the user. Any users that you grant access will be able to access buckets and files using their AWS Access Key IDs and Secret Access Keys.

Permissions Table - Columns

Each column represents a permission. The permission in a grant describes the type of access to be granted to the respective grantee. There are five types of permissions:

  • Full Control
  • Read
  • Write
  • Read Permissions (READ ACP)
  • Write Permissions (WRITE ACP)

Full Control - Provides Read, Write, Read ACP and Write ACP permissions. It does not provide any additional rights and is included only for convenience.

Read - When applied to the bucket, grants permissions to list the bucket. When applies to the file, this grants permissions to read the file data and/or metadata.

Write - When applied to the bucket, grants permission to create, overwrite, and delete any file in the bucket. This permission is not supported for files.

Read Permissions (READ ACP) - Allows a user to read permissions for the specified bucket or file.

Write Permissions (WRITE ACP) - Allows a user to overwrite permissions for the specified bucket or file. The owner of a bucket or file always has this permission implicitly. Granting this permission is equivalent to granting Full Control because the grant recipient can make any changes to the permissions.

Make Public button allows you to grant Read permission to All Users making the file available for everyone.

Make Private button allows you to reset permissions and make selected file(s) private.

More -> Add user by Email/ID button allows you to add user by Email/ID

More -> Remove user will delete selected user from the grantees list.

Apply for all subfolders and files - enable this checkbox if you want to apply permissions to all subdirectories and files.

Apply - apply changes.

Reload - reload permissions (all unsaved changed will be lost)
