title: AWS S3 bucket access token
body: <p>I have an aws s3 bucket and want to share and sync data with my team and some other individuals (and later access this data in the cloud). This is easy with the aws cli (<code>aws s3 sync ...</code>), but since we are now in the situation where multiple other individuals from outside are involved, they don't have an aws-account.</p>
  
  <p>What is the preferred strategy here? Is there a way to get something like a read/write access-token, which then could get passed to the aws-cli?</p>
