Strong password checking lets you define criteria for new passwords; for example, you can specify that new passwords cannot be duplicates of old ones or contain the same characters as login names.
To configure strong passwords:
On the Settings tab, click Shopper.
Select one or more strong password settings.
If you select Minimum Password Length, enter a number that specifies the minimum number of characters.
If you select Cannot Be A Previous Password, enter a number that specifies how many most recent passwords cannot be used.
If you select Expire Password, enter a number that specifies the number of days until a new password expires.
Click Save.
