Using the MS Authenticator on multiple devices RRS feed

  • Question

  • Hi,

    I am wondering how do I configure the MS Authenticator App on multiple iphones? I have MS Authenticator set up and functioning on my primary iphone, but I would like to use it on my older iphone as a back up, is this possible for all the 2FA accounts I am using? I did set it up for my Microsoft account for 2 phones (so I do have the App installed on 2 devices) and it seems to have both in Sync and works, but I am concerned about other accounts. These are banking accounts and I just don't get how the syncing on each phone works? Could I add as many devices as I wanted?

    I really appreciate your diligence and support!

    Thanks, Nick

  • Hi Nick,

    Microsoft Authenticator app support configure Microsoft accounts (personal account) to multiple devices.

    But for security purposes, MFA does not support for work or school account with multiple devices. It is a by design behavior.

    Best regards,

    Jason

  • Hi,

    is there any official document stating this by-design behavior related to work/school accounts?

    Thanks!

  • Hi Pyjo,

    Sorry, I can't find any official document about it, but I have test it several times, work or school account does not support multiple devices.

  • If you load cortana on all of your devices and set it to show notifications across your devices, you can acknowledge the multifactor notifications/view code from the other devices.  I do this today for my work azure MFA.  Basically, I have the azure mfa application on my phone along with Cortana.  When I get the notifications on my phone, they also pop up on my cortana on my surface pro 3.  Not perfect, but maybe this will work for you.

  • Ok so don't know if people are still trying to set this up- or whether MS still 'don't support' setting up the ms authenticator for one account across multiple devices- but i have managed to set it up in a round about way that probably shouldn't have worked if the above is accurate.

    scenario assumes you already have it setup and working on one of your devices:

    step 1- setup authenticator on the secondary device.

    step 2- for those admins out there, you need to disable MFA on the account and then re-enable.

    step 3- now add work account via the plus symbol in ms authenticator on your secondary device (do not make any changes to the authenticator on your primary device).

    step 4- scan the QR code and follow the prompts to verify activation.

    Now sign out of your account in a browser and re-login- do this twice and try the code from authenticator on your primary and secondary device. They will be different but both seem to be accepted.

    I can't see any reason why you couldn't expand this process to a third device if you needed to, personally wouldn't suggest going over two. I don't know whether MS have enabled this a feature recently or if this is a workaround. Either way.

  • It looks like there's now a process for this, linked to not receiving notifications, so presumably you have to manually refresh the app to pickup the authentication request...

    I've not tested this!

  • In late 2018, Microsoft added support for multiple authenticator apps to be linked to a MFA enabled user (push notications are sent to multiple devices).

    To add a second device, just run the MFA setup again: https://aka.ms/MFASetup

    Hope this helps others :)

  • Where do I check the QR code that you've mentioned under Step 4?
