Minimum password length
This security setting determines the least number of characters that a password for a user account may contain.
The maximum value for this setting is dependent on the value of the Relax minimum password length limits setting.
If the Relax minimum password length limits setting is not defined, this setting may be configured from 0 to 14.
If the Relax minimum password length limits setting is defined and disabled, this setting may be configured from 0 to 14.
If the Relax minimum password length limits setting is defined and enabled, this setting may be configured from 0 to 128.
Setting the required number of characters to 0 means that no password is required.
Note: By default, member computers follow the configuration of their domain controllers.
Default:
7 on domain controllers.
0 on stand-alone servers.
Configuring this setting than 14 may affect compatibility with clients, services, and applications. Microsoft recommends that you only configure this setting larger than 14 after using the Minimum password length audit setting to test for potential incompatibilities at the new setting.
