There's no Admin UI for changing the password policy. You'll need to navigate to the XWiki.Registration page and edit it. Then find and modify the following block:

#set($field = {
 'name' : 'register_password',
 'label' : $services.localization.render('core.register.password'),
 'params' : {
   'type' : 'password',
   'autocomplete' : 'off',
   'size' : '60'
 },
 'validate' : {
   'mandatory' : {
     'failureMessage' : $services.localization.render('core.validation.required.message')
   },
   'regex' : {
     'pattern' : '/.{6,}/',
     'failureMessage' : $services.localization.render('xe.admin.registration.passwordTooShort')
   }
 }
})

Specifically you may want to modify the regex pattern.
