IAM: Allows IAM users to self-manage an MFA device

This example shows how you might create an identity-based policy that allows IAM users to self-manage their multi-factor authentication (MFA) 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.
