How to sign in to Microsoft Authenticator. When the phone is lost, the authentication code cannot be sent.

I lost my phone. In that phone is my Microsoft Authenticator account. Now I want to sign in to my Microsoft Authenticator account on my new phone but I can't. Because it requires an authentication code in my old phone. What should I do? I can't sign in to Microsoft 365 without a Microsoft Authenticator account. Please help me.

    Sounds like you'll need an account admin to reset the account so a new QR code can be generated with which you can relink the authentication device to your account.
