By default, Active Directory is configured with a default domain password policy. This policy defines the password requirements for Active Directory user accounts such as password length, age and so on.

This password policy is configured by group policy and linked to the root of the domain. To view the password policy follow these steps:

1. Open the group policy management console

2. Expand Domains, your domain, then group policy objects
3. Right click the default domain policy and click edit

4. Now navigate to Computer Configuration\Policies\Windows Settings\Security Settings\Account Policies\Password Policy
Important: The default password policy is applied to all computers in the domain. If you want to apply different password policies to a group of users then it is best practice to use fine grained password policy.
