Microsoft Authenticator not syncing across devices

[Quartz]

I've just got my new iPad, updated it, and have installed Microsoft Authenticator. I've put in the same credentials as on my phone but none of the accounts have been copied over.

I want to be able to use both my iPad and my phone as 2FA devices, especially as I may be reformatting my phone soon.

I'm guessing there's some PEBKAC issue I've overlooked.

Microsoft Authenticator doesn't support multiple devices last time I checked, you can back up and restore between devices but you can't use them at the same time.

You'll want to use Authy instead which supports this.

You can't just clone/backup+restore or otherwise transfer the authentication config - if you could it wouldn't be very secure.

What you can do though is use this page:

https://mysignins.microsoft.com/security-info

Go to Add Method, authenticator app, and set it up on your other device. Only one can be set as "preferred" which it will default to using, but if it tries to send a notification to that device when you are using a different one, there is a link saying something like "sign in another way".
