Account Policies

Account policies can be used to enforce long, difficult, frequently changed passwords and make it hard for users to recycle the same passwords when forced to change. You should lock out accounts that fail several login attempts, locally or over the LAN.

  • The account policies category contains the password policy and the account lockout policy. Account policies do not affect domain accounts and must be configured at the domain level.

  • The password policy controls password characteristics for local user accounts. The available settings include:

  • Policy Description Default Minimum Maximum
    Enforce Password History Keeps track of user's password History Remember 0 passwords Same as default Remember 24 passwords
