As an account administrator, you can require local users (those authenticated by Splunk AppDynamics) to use strong passwords.

Enforcement of strong password requirements is not automatic. Users can configure passwords of any length or complexity unless you enforce strong password requirements. Navigate to Settings > Administration > Authentication Provider. Mark the Require Strong Passwords checkbox to enable the requirement.

Once set, passwords must meet the complexity requirements shown in the Authentication Provider tab. The requirements include having at least eight characters, containing both upper and lower case letters, and so on.

Passwords set by users after you enable this requirement must meet the requirements of the Controller. Changing this option does not affect previously set passwords. Existing weak passwords will continue to work after you enable strong passwords.
