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