I have deleted my authenticator app by mistake, and now unable to login to o365 since its sending authentication notification.

    Hi,

    Can you restore it from backup if you configured during the setup of Auth App? If not I will suggest you to contact the Tenant admin to reset the MFA settings for your account so you can set it again. If you are the only Tenant admin I will suggest you to raise a call with the global support team and data protection team - https://support.microsoft.com/en-us/topic/global-customer-service-phone-numbers-c0389ade-5640-e588-8b0e-28de8afeb3f2

    Hope this helps.
