INC Secure Workaround for MFA

How to disable Multi-Factor Authentication for individual users in a secure way

In some cases Nimbus will require you to invite Guest Accounts to support extended features on your Tenant. We realize that not using MFA for presence accounts is a big limitation. If your IT policy mandates MFA on all accounts, there is a workaround that whitelists IP ranges. To circumvent this problem you can use the following workaround:

  • Add trusted Locations with the Nimbus Server IP Addresses (Switzerland)
  • Add a conditional access policy to limit the access to the given trusted location.

Add Trusted Location

  1. Go to Named locations within Azure Portal (https://portal.azure.com)
  2. Add a new IP ranges location
  3. Enter a Name and add the IP addresses for the location and check the Mark as trusted location option
  4. Add all IP addresses for the location (see table below)

    and click on Create

Add a conditional access policy

  1. Go to the Azure portal (https://portal.azure.com)
  2. Switch to Conditional Access and select Policies
  3. Select an existing you want to change or create a new policy and configure the Condition section to add your trusted location as excluded from the MFA policy
