The strength of all user passwords can be configured here. Passwords may not be shorter than a minimum length of 8 characters, but a higher minimum length can be configured. Different character sets (like letters in general, lowercase letters, uppercase letters, digits or special characters) can be forced to be contained in all passwords. After setting password policies, all new and all changed passwords must follow these. Existing passwords will not be changed, even if they do not conform the new password policies.
