# Use `EnableMfaDevice` with a CLI
`EnableMfaDevice`

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

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

**AWS CLI**  
**To enable an MFA device**  
After you use the `create-virtual-mfa-device` command to create a new virtual MFA device, you can assign the MFA device to a user. The following `enable-mfa-device` example assigns the MFA device with the serial number `arn:aws:iam::210987654321:mfa/BobsMFADevice` to the user `Bob`. The command also synchronizes the device with AWS by including the first two codes in sequence from the virtual MFA device.  

```
aws iam enable-mfa-device \
    --user-name Bob \
    --serial-number arn:aws:iam::210987654321:mfa/BobsMFADevice \
    --authentication-code1 123456 \
    --authentication-code2 789012
```
This command produces no output.

#### [ PowerShell ]

**Tools for PowerShell V4**  
**Example 1: This command enables the hardware MFA device with the serial number `987654321098` and associates the device with the user `Bob`. It includes the first two codes in sequence from the device.**  

```
Enable-IAMMFADevice -UserName "Bob" -SerialNumber "987654321098" -AuthenticationCode1 "12345678" -AuthenticationCode2 "87654321"
```
**Example 2: This example creates and enables a virtual MFA device. The first command creates the virtual device and returns the device's object representation in the variable `$MFADevice`. You can use the `.Base32StringSeed` or `QRCodePng` properties to configure the user's software application. The final command assigns the device to the user `David`, identifying the device by its serial number. The command also synchronizes the device with AWS by including the first two codes in sequence from the virtual MFA device.**  

```
$MFADevice = New-IAMVirtualMFADevice -VirtualMFADeviceName "MyMFADevice"
# see example for New-IAMVirtualMFADevice to see how to configure the software program with PNG or base32 seed code
Enable-IAMMFADevice -UserName "David" -SerialNumber -SerialNumber $MFADevice.SerialNumber -AuthenticationCode1 "24681357" -AuthenticationCode2 "13572468"
```
+  For API details, see [EnableMfaDevice](https://docs.aws.amazon.com/powershell/v4/reference) in *AWS Tools for PowerShell Cmdlet Reference (V4)*. 

**Tools for PowerShell V5**  
**Example 1: This command enables the hardware MFA device with the serial number `987654321098` and associates the device with the user `Bob`. It includes the first two codes in sequence from the device.**  

```
Enable-IAMMFADevice -UserName "Bob" -SerialNumber "987654321098" -AuthenticationCode1 "12345678" -AuthenticationCode2 "87654321"

Enable-IAMMFADevice -UserName "David" -SerialNumber -SerialNumber $MFADevice.SerialNumber -AuthenticationCode1 "24681357" -AuthenticationCode2 "13572468"
