# IAM – Password Policy

• Strong passwords = higher security for your account

• In AWS, you can set a password policy:

* Set a minimum password length
* Require specific character types:
  * including uppercase letters
  * lowercase letters
  * numbers
  * non-alphanumeric characters
* Allow all IAM users to change their passwords
* Require users to change their password after some time (password expiration)
* Prevent password re-use
