Using Local Security Policy.
Type Local Security Policy in the start menu search and press Enter. The LSP window will open. Now from the left pane, choose Password Policy from under Account Policies. Now on the right side six options will be listed.
Details of each of those options are listed below.
Enforce Password history: This security setting determines the number of unique new passwords that have to be associated with a user account before an old password can be reused. The value must be between 0 and 24 passwords. This policy enables administrators to enhance security by ensuring that old passwords are not reused continually.
Maximum password age: This security setting determines the period of time (in days) that a password can be used before the system requires the user to change it. You can set passwords to expire after a number of days between 1 and 999, or you can specify that passwords never expire by setting the number of days to 0. If the maximum password age is between 1 and 999 days, the Minimum password age must be less than the maximum password age. If the maximum password age is set to 0, the minimum password age can be any value between 0 and 998 days.
Minimum password age: This security setting determines the period of time (in days) that a password must be used before the user can change it. You can set a value between 1 and 998 days, or you can allow changes immediately by setting the number of days to 0. The minimum password age must be less than the Maximum password age, unless the maximum password age is set to 0, indicating that passwords will never expire. If the maximum password age is set to 0, the minimum password age can be set to any value between 0 and 998.
Minimum password length: This security setting determines the least number of characters that a password for a user account may contain. You can set a value of between 1 and 14 characters, or you can establish that no password is required by setting the number of characters to 0.
Password must meet complexity requirements: This security setting determines whether passwords must meet complexity requirements. If this policy is enabled, passwords must meet the following minimum requirements:
– Not contain the user’s account name or parts of the user’s full name that exceed two consecutive characters
– Be at least six characters in length
– Contain characters from three of the following four categories:
– Be at least six characters in length
– Contain characters from three of the following four categories:
- English uppercase characters (A through Z)
- English lowercase characters (a through z)
- Base 10 digits (0 through 9)
- Non-alphabetic characters (for example, !, $, #, %)
Complexity requirements are enforced when passwords are changed or created.
