|Multi-Factor Authentication (MFA)-protected API access support||
Amazon S3 now supports MFA-protected API access, a feature that can enforce AWS
MFA validation for access to your resources. AWS Multi-Factor
Authentication provides an extra level of security you can apply to your AWS
environment. It requires that users posess an MFA device, which they then use to provide a valid MFA code. For more information,
go to AWS Multi-Factor Authentication.
You can enforce the MFA authentication requirement in a bucket policy by adding a condition using the aws:MultiFactorAuthAge key. For an example policy, go to Example Cases for Amazon S3 Bucket Policies.
