Password Policy in Kerio Connect

Author: Vladyslav Velychko Updated

Overview

Kerio Connect Administrators can implement a strong complex password requirement, enable password expiration limit, and protect users against password guessing attacks.

Users may not be able to login to their accounts it the weak (easy) password was chosen. That's why it's recommended to follow best practices for securing Kerio Connect user passwords.

 

Prerequisites

Access to Kerio Connect Administration

Solution

Creating Strong User Passwords

Strong user passwords should be long and complex. The following guidelines may help you in advising your users:

  • Passwords should be at least 8 characters long.
  • Passwords should contain all of the following:
    • Lowercase letters
    • Uppercase letters
    • Numbers
    • Special characters
  • Users should change their passwords often.
