A password policy is a set of rules and guidelines that dictate how users should create and manage their passwords within an organization. These policies typically include requirements for minimum password length, complexity, and expiration, as well as guidelines for avoiding the use of easily guessable information, such as personal information or common words. The goal of a password policy is to help protect against unauthorized access to systems and data by ensuring that user passwords are strong and difficult to crack.

Creating a password policy typically involves the following steps:

  • Define the scope of the policy: Determine which systems, applications, and data the policy will apply to, and who will be required to comply with it.
  • Establish password requirements: Decide on minimum length, complexity, and expiration requirements for passwords. Examples of complexity requirements include the use of a mix of upper and lowercase letters, numbers, and special characters.
  • Prohibit the use of easily guessable information: Outline what types of information should not be used in passwords, such as personal information or common words.
  • Communicate the policy to users: Clearly communicate the policy to all users who will be affected by it, and provide them with guidance on how to create strong passwords that comply with the policy.
  • Monitor and enforce compliance: Regularly monitor user passwords to ensure compliance with the policy, and take appropriate action if a user's password does not comply.
  • Review and update the policy: Review the policy regularly to ensure it is still effective and relevant, and update it as needed to reflect new security threats or changes in your organization.
  • It is also important to note that it's a good practice to use a password manager, this tool will help you to generate complex passwords and store them securely, also it will help to enforce the password policy in your organization.

    Setting it up on a Windows Domain

    The Windows Group Policy Editor (GPE) is a tool that allows you to manage and configure various settings for computers and users in a Windows domain. To create a password policy using the GPE, follow these steps:

  • Open the GPE by typing "gpedit.msc" in the Start menu search box and pressing Enter.
  • In the left pane, navigate to Computer Configuration > Windows Settings > Security Settings > Account Policies > Password Policy.
  • In the right pane, you will see several options for configuring password policies, including:
    • Minimum Password Length: This sets the minimum number of characters required for a password.
    • Password Complexity: This option requires that passwords contain a mix of uppercase and lowercase letters, numbers, and special characters.
    • Password History: This option prevents users from reusing the same password for a certain number of password changes.
    • Maximum Password Age: This sets the number of days that a password can be used before it expires and must be changed.
    • Minimum Password Age: This sets the number of days that must pass before a password can be changed.
  • Configure the settings as desired.
  • Close the GPE, and the policy will take effect on the next computer startup or user logon.
  • Please note that these steps apply to Windows Server operating systems that have Group Policy Editor installed, Windows 10 Pro and Windows 10 Enterprise also have this tool, but Windows 10 Home doesn't have it.

    Additionally, if you want to change the password policy for users on multiple computers or servers in a Windows domain, you can use the Group Policy Management Console (GPMC) to create and edit a Group Policy Object (GPO) that applies the password policy to all computers and users in the domain.
