ListMFADevices
Lists the MFA devices for an IAM user. If the request includes a IAM user name, then this operation lists all the MFA devices associated with the specified user. If you do not specify a user name, IAM determines the user name implicitly based on the AWS access key ID signing the request for this operation.
You can paginate the results using the MaxItems
and Marker
parameters.
Request Parameters
For information about the parameters that are common to all actions, see Common Parameters.
- Marker
-
Use this parameter only when paginating results and only after you receive a response indicating that the results are truncated. Set it to the value of the
Marker

Use this only when paginating results to indicate the maximum number of items you want in the response. If additional items exist beyond the maximum you specify, the
IsTruncated
response element istrue
.If you do not include this parameter, the number of items defaults to 100. Note that IAM might return fewer results, even when there are more results available. In that case, the
IsTruncated
response element returnstrue
, andMarker
contains a value to include in the subsequent call that tells the service where to continue from.Type: Integer

after every call to ensure that you receive all your results.Type: Boolean
