Use PutBucketVersioning with an AWS SDK or CLI

The following command enables versioning on a bucket named my-bucket:

aws s3api put-bucket-versioning --bucket my-bucket --versioning-configuration Status=Enabled

The following command enables versioning, and uses an mfa code

aws s3api put-bucket-versioning --bucket my-bucket --versioning-configuration Status=Enabled --mfa "SERIAL 123456"

    /**
     * Enables bucket versioning for the specified S3 bucket.
     *
     * @param s3Client the S3 client to use for the operation
     * @param bucketName the name of the S3 bucket to enable versioning for
     */
    public static void enableBucketVersioning(S3Client s3Client, String bucketName){
        VersioningConfiguration versioningConfiguration = VersioningConfiguration.builder()
            .status(BucketVersioningStatus.ENABLED)
            .build();

        PutBucketVersioningRequest versioningRequest = PutBucketVersioningRequest.builder()
            .bucket(bucketName)
            .versioningConfiguration(versioningConfiguration)
            .build();

        s3Client.putBucketVersioning(versioningRequest);
        System.out.println("Bucket versioning has been enabled for "+bucketName);
    }
