Send MFA token with access key for S3 bucket

Question

I am trying to add MFA (Multi Factor Authentication) in my application, where i am going to store object in aws S3 bucket. I went through AWS documentation but could not find anything where we can pass MFA tokedn while sending any request to AWS programmatically in C#.

 

Here is my working code snippet without MFA,

 

var awsCredentials = new BasicAWSCredentials(accessKey, secretKey);

_client = new AmazonS3Client(awsCredentials, Amazon.RegionEndpoint.USEast1);

var putRequest = new PutObjectRequest {

BucketName = ConfigurationManager.AppSettings["S3BucketName"],

Key = fileName, FilePath = localFilePath,

ContentType = "image/" + Path.GetExtension(fileName),

CannedACL = S3CannedACL.PublicRead };

var req = JsonConvert.SerializeObject(putRequest);

 

I am expecting to add MFA authentication token to this above code.

Thanks,
