Unable to log into azure subscription

Question

Changed mobile phone with Authenticator application.

Unable to log into azure subscription as it requires MFA, my new phone with authenticator application is not aware of the subscription I am trying to log into.

No other admins exist within the AAD for this subscription. I was logging in with a guest account which had global admin rights.

Answer 1

Hello
Make sure you used the account which is subscriped to your azure account to login to your phone with the Authenticator application, then the app will be able to know about your subscription

Thank you for your post!

Since it sounds like you moved to a new mobile device, adding the Authenticator app to your new device doesn't automatically remove the app from your old device. Even deleting the app from your old device isn't enough. You must both delete the app from your old device AND tell Microsoft or your organization to forget and unregister the old device.

• To remove the app from a device using a personal Microsoft account, go to the two-step verification area of your Account Security page and choose to turn off verification for your old device.
• To remove the app from a device using a work or school Microsoft account, go to the two-step verification area of either your My Apps page or your organization's company portal to turn off verification for your old device.
