<a name="iam_example_iam_ListMfaDevices_section"></a>

The following code examples show how to use `ListMfaDevices`.

------
#### [ CLI ]

**AWS CLI**  
**To list all MFA devices for a specified user**  
This example returns details about the MFA device assigned to the IAM user `Bob`.  

```
aws iam list-mfa-devices \
    --user-name Bob
```
Output:  

```
{
    "MFADevices": [
        {
            "UserName": "Bob",
            "SerialNumber": "arn:aws:iam::123456789012:mfa/Bob",
            "EnableDate": "2019-10-28T20:37:09+00:00"
        },
        {
            "UserName": "Bob",
            "SerialNumber": "GAKT12345678",
            "EnableDate": "2023-02-18T21:44:42+00:00"
        },
        {
            "UserName": "Bob",
            "SerialNumber": "arn:aws:iam::123456789012:u2f/user/Bob/fidosecuritykey1-7XNL7NFNLZ123456789EXAMPLE",
            "EnableDate": "2023-09-19T02:25:35+00:00"
        },
        {
            "UserName": "Bob",
            "SerialNumber": "arn:aws:iam::123456789012:u2f/user/Bob/fidosecuritykey2-VDRQTDBBN5123456789EXAMPLE",
            "EnableDate": "2023-09-19T01:49:18+00:00"

#### [ PowerShell ]

**Tools for PowerShell V4**  
**Example 1: This example returns details about the MFA device assigned to the IAM user `David`. In this example you can tell that it is a virtual device because the `SerialNumber` is an ARN instead of a physical device's actual serial number.**  

```
Get-IAMMFADevice -UserName David
```
**Output:**  

```
EnableDate                  SerialNumber                           UserName
----------                  ------------                           --------
4/8/2015 9:41:10 AM         arn:aws:iam::123456789012:mfa/David    David
```
+  For API details, see [ListMfaDevices](https://docs.aws.amazon.com/powershell/v4/reference) in *AWS Tools for PowerShell Cmdlet Reference (V4)*. 

**Tools for PowerShell V5**  
**Example 1: This example returns details about the MFA device assigned to the IAM user `David`. In this example you can tell that it is a virtual device because the `SerialNumber` is an ARN instead of a physical device's actual serial number.**  

```
Get-IAMMFADevice -UserName David
```
**Output:**  

```
EnableDate                  SerialNumber                           UserName
----------                  ------------                           --------
