You can set up a custom Password Policy for all account contacts on the account the following way:

1. Control Panel > Account > Security Policies > Contacts password policy
    

   

2. Specify custom policy settings:
   • password complexity (default or strong)
   • minimum password length
   • password expiration period
     Note: The password expiration can be reduced but cannot be disabled or extended beyond 365 days. Disabling the Set passwords to expire setting will reset password expiration to the 365 days default.
   • account contact lock settings
     and click Save Changes.
      

     

   Note: If you enable password expiration you can check the password expiration date for individual account contact by navigating to Control Panel > Account > Account contacts > click on Account Contact Display Name > review Password expiration date.
   Note: Shared accounts contacts, who manage several accounts might have the stronger password policy enabled on other accounts. The strongest compilation of policies will be applied to this shared account contact
