## Manage your identity source

* **Note**\
  IAM Identity Center does not support SAMBA4-based Simple AD as an identity source.

## Multi-factor authentication

* **Important**\
  As a security best practice, we strongly recommend that you enable multi-factor authentication. MFA provides a simple and secure way to add an extra layer of protection on top of the default authentication mechanism of user name and password.
