Is there any way to use boto3 anonymously

Question

Using boto I was able to connect to the public S3 buckets without having credentials by passing the anon= keyword argument.

s3 = boto.connect_s3(anon=True)

Can I do this with boto3?

Answer 1

Yes. Your credentials are used to sign all the requests you send out, so all you have to do is configure the client to not perform the signing step at all. You can do this as follows:

import boto3
from botocore import UNSIGNED
from botocore.client import Config

s3 = boto3.client('s3', config=Config(signature_version=UNSIGNED))
# Use the client
