Can I use boto3 anonymously?

Question

With boto I could connect to public S3 buckets without credentials by passing the anon= keyword argument.

s3 = boto.connect_s3(anon=True) 

Is this possible with boto3?

Answer 1

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