How to upload to AWS S3 directly from browser using a pre-signed URL instead of credentials?

Question

We\'d like to use Javascript AWS SDK to upload files to S3, but without using credentials at all. Uploading using credentials works, but we cannot generate an AWS IAM user f

Answer 1

I could suggest two approaches:

1- You could generate a pre-signed form in your app, with one credential

See doc: http://docs.aws.amazon.com/AmazonS3/latest/dev/HTTPPOSTForms.html

2- You could use web identity federation and use login with google, facebook or amazon:

See doc: http://docs.aws.amazon.com/AWSJavaScriptSDK/guide/browser-configuring-wif.html
