If you are in the old Amazon S3 console, to use the new console, choose Opt In in the following box, which appears on the old Amazon S3 console home page.
The topics in this section explain how to use the Amazon S3 console to set bucket and object permissions.
Bucket permissions specify which users are allowed access to the objects in a bucket and what permissions you have granted them. For example, one user might have only read permission while another might have read and write permissions.
Bucket and object permissions are completely independent. An object does not inherit the permissions from its bucket. For example, if you create a bucket and grant write access to another user, you will not be able to access that user’s objects unless the user explicitly grants you access.
