Unable to login to Microsoft account after loss of MFA device

Question

Having just setup a Microsoft account, along with Microsoft 365 for Business, setting up MFA, and being the only admin user I then proceeded to loose access permanently to the Microsoft Authenticator that contained said MFA credentials.

When trying to login I get stuck in a loop, being asked to either:

"Open your Authenticator app, and enter the number shown to sign in.​​"

"Enter the code displayed in the Microsoft Authenticator app on your mobile device"

Neither of which I can fulfil and these are the only 2 options I'm presented with!

I've searched high and low for a solution but no luck, especially as MFA is involved.

Before I lost access I was able to verify our companies domain – not sure if that'll help get re-verified, but here's hoping!

Can anyone please suggest next steps to escalate this with the relevant people @ Microsoft?

Thanks,

Robin

Hi

I would suggest raising a ticket using your local number from one of the Global Support numbers listed here:

They should be able to assist. You will need to provide proof that you are the owner of the Subscription.

Hope this helps,
