1.1.4 Ensure 'Minimum password length' is set to '14 or more characters'


This policy setting determines the least number of characters that make up a password for a user account. There are many different theories about how to determine the best password length for an organization, but perhaps 'passphrase' is a better term than 'password.' In Microsoft Windows 2000 and newer, passphrases can be quite long and can include spaces. Therefore, a phrase such as 'I want to drink a $5 milkshake' is a valid passphrase; it is a considerably stronger password than an 8 or 10 character string of random numbers and letters, and yet is easier to remember. Users must be educated about the proper selection and maintenance of passwords, especially with regard to password length. In enterprise environments, the ideal value for the Minimum password length setting is 14 characters, however you should adjust this value to meet your organization's business requirements.

Note: All recommendations in Section 1.1 (Password Policy) are only applied to Local and Microsoft accounts and not Domain accounts. For more information, please see the references section below.

Note #2: If Windows Hello for Business is used, an exception to this recommendation might be needed.

The recommended state for this setting is: 14 or more characters.


Types of password attacks include dictionary attacks (which attempt to use common words and phrases) and brute force attacks (which try every possible combination of characters). Also, attackers sometimes try to obtain the account database so they can use tools to discover the accounts and passwords.


Requirements for extremely long passwords can actually decrease the security of an organization, because users might leave the information in an insecure location or lose it. If very long passwords are required, mistyped passwords could cause account lockouts and increase the volume of help desk calls. If your organization has issues with forgotten passwords due to password length requirements, consider teaching your users about passphrases, which are often easier to remember and, due to the larger number of character combinations, much harder to discover.

Note: Older versions of Windows such as Windows 98 and Windows NT 4.0 do not support passwords that are longer than 14 characters. Computers that run these older operating systems are unable to authenticate with computers or domains that use accounts that require long passwords.

Note #2: If Windows Hello for Business is used, an exception to this recommendation might be needed as a PIN length of 14 could be considered unrealistic.


To establish the recommended configuration, set the following Device Configuration Policy to Required and 14 or more characters:
