# IAM: Allows IAM users to self-manage an MFA device
<a name="reference_policies_examples_iam_mfa-selfmanage"></a>

This example shows how you might create an identity-based policy that allows IAM users to self-manage their [multi-factor authentication (MFA)](id_credentials_mfa.md) device. This policy grants the permissions necessary to complete this action programmatically from the AWS API or AWS CLI.

**Note**  
If an IAM user with this policy is not MFA-authenticated, this policy denies access to all AWS actions except those necessary to authenticate using MFA. If you add these permissions for a user that is signed in to AWS, they might need to sign out and back in to see these changes.
