How do I reset my Microsoft 365 password?

It’s the beginning of a new year and hopefully you have had a good break over the Christmas summer period and have truly switched off from work. One of the most common calls we get at CommSys at this time of year is “I’ve forgotten my password and how do I reset it?” If you have forgotten your password you will need to give the CommSys team a call on 1300 553 084 to have us reset your password.  

We recommend you update your password every few months to keep your account secure and to avoid data breaches. In order to reset your Microsoft 365 password, follow these simple instructions. Please note that this method only works if you know the existing account password.

  1. Open your internet browser and go to:
  2. Sign in with your Microsoft 365 email address and password 
  3. Select the settings cog in the top right-hand corner, then click change your password
  4. Enter your existing password then type in a new password.  Remember, the new password must meet your organisation’s password complexity requirements
  5. Click Submit



Today, traditional simple passwords are no longer secure enough. We recommend that passwords be made by stringing four or more words together into a sentence that is easy to remember but long enough that it’s impractical to guess or crack by brute-force. A password that is 12 characters long with capital letters would take roughly 600 years to crack via a brute-force attack.

To increase security further, we suggest implementing a multi-factor authentication (MFA) solution. MFA is an electronic authentication method that requires the user to provide two or more forms of identity verification before they’re allowed access to a website, network, or application.  You can read more about MFA and its benefits here –  

If you need help resetting your Microsoft 365 password or would like to implement an MFA solution for your organisation to increase your security, please get in touch with our support team on 1300 553 084.
