How do I grant anonymous access
to an Amazon S3 bucket?
You use an Amazon S3 bucket policy that specifies a wildcard (*) in the principal
element, which means anyone can access the bucket. With anonymous access, anyone (including
users without an AWS account) will be able to access the bucket. For a sample policy, see
Example Cases for Amazon S3
Bucket Policies in the Amazon Simple Storage Service User Guide.
I'm signed in as an AWS account
root user. Why can't I access an Amazon S3 bucket under my account?
In some cases, you might have an IAM user with full access to IAM and Amazon S3. If the
IAM user assigns a bucket policy to an Amazon S3 bucket and doesn't specify the root user as a
principal, the root user is denied access to that bucket. However, as the root user, you can still
access the bucket. To do that, modify the bucket policy to allow root user access from the Amazon S3
console or the AWS CLI. Use the following principal, replacing
123456789012 with the ID of the AWS account.
"Principal": { "AWS": "arn:aws:iam::123456789012:root" }
