# Use `ResyncMfaDevice` with a CLI
<a name="iam_example_iam_ResyncMfaDevice_section"></a>

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

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

**AWS CLI**  
**To synchronize an MFA device**  
The following `resync-mfa-device` example synchronizes the MFA device that is associated with the IAM user `Bob` and whose ARN is `arn:aws:iam::123456789012:mfa/BobsMFADevice` with an authenticator program that provided the two authentication codes.  

```
aws iam resync-mfa-device \
    --user-name Bob \
    --serial-number arn:aws:iam::210987654321:mfa/BobsMFADevice \
    --authentication-code1 123456 \
    --authentication-code2 987654
```
This command produces no output.
