Conditional Access MFA for Admin Policy


I have 2 Global AAD accounts, for the sake of this exercise call them Account1 and Account 2.

  • Account1 is my main Global Admin work account.
  • Account2 is my Break Glass account.
  • I have MFA set up on Account1, but don't have MFA set up on Account 2.

I have set up Conditional Access Policy for account Assignments:

  • Account1 Included
  • Account 2 Excluded

I then set Grant Access to MFA.

Now my expectation is MFA will be asked for when SSO with Account1, but with Account2, SSO will just ask for the password and not follow up with MFA.

Is this correct?

I haven't yet tested it out as yet, because I am 'leery' that I might lock myself out of all Global Admin Accounts.

To ere on the safe side, I have added a third Global Admin Account3

    I would recommend all users including global admins in your tenant to register for MFA even though they are not prompted for MFA. This will ensure that you are not blocked to access the Azure AD portal even if MFA is enforced through conditional access policy.

    In your scenario there are 2 accounts. If you want to MFA to be prompted only for account 1.
    In this scenario while configuring MFA, you can include only the user accounts to whom MFA needs to be prompted.

    If you have multiple groups of accounts and if you want to exclude only one account from the group, then you can use the exclude option which configuring conditional access policy.

    After creating the policy, you can use whatif tool to confirm what all policies are getting applied to specific account.
    Refer below article to know more about what if tool,

    This way you can create a policy and run what if tool against one admin account and confirm regarding MFA prompt.

    Do let me know if you have any further questions on this

    Hi @Anonymous

    If you exclude Account2 from a Conditional Access Policy then it will not be affected by the change. From my understanding you are trying to force MFA to all accounts (Account1 included, but Account2 excluded). If you follow proper procedures for excluding Account2 you will be set.

    It even states in the documentation to exclude one Administrator account so you don't lock yourself out:
