Answer is: Fortunately, NO!
Simply go to the following link, enter your Aon email and current Aon password - you may be prompted to send an SMS code to your phone for authentication. Do so and you should be granted access to Workday which can be accessed from any computer you choose.
If you have issues accessing, then your Aon password is likely expired or you are locked out. As long as you are logging into VPN regularly and maintaining your password via Nomad, you shouldn't have issues!
