I can't log back into my microsoft authenticator app.

My phone was stolen recently and I didn’t save any of the codes I now realize were needed. I can’t log back into the app now because I don’t have my former phone (and I have no way of getting it back) and I need it to log into some school related apps (teams for example). I did not know that I could save it on my iCloud so that’s not an option either.
My question is this: how do I log back in now?

    Facing the exact same issue. Microsoft needs to fix this bug as admin are not always responsive for this. How can a user fix this issue if he is logged out of all devices.

    My issue is now fixed.

    My administrator was able to login to the 'background' of 365 and could input my phone number against my account. This allowed me to send an authentication code via text to my mobile number and I now had access to the Security Info page, so I have re-done the QR code thing again for the app.

    All now resolved!

    Hope this comment helps others.

    I had the same issue, but is fixed now.

    You just have to go to your outlook account configuration.
    Then to security info to delete the prevoius method authentication. (You can find it here -> https://learn.microsoft.com/en-us/azure/active-directory/user-help/security-info-setup-auth-app)
    And then add a new method of Microsoft Authentication type.
    This will generate a new QR Code that you can scan from your phone app.

    Hope it helps.
