What happens if I lose my phone with Microsoft Authenticator?
If you lose your phone with the authenticator, getting access to your accounts should not be a problem. Simply log into your non-Microsoft accounts and enter one of the codes you saved from the authenticator when prompted. Your personal and business security is crucial when operating online accounts.
If solely unregistering your old device from the Account Security or MyApps portal doesn't work, you have to delete the app from your old device. However, because you lost your old device, I'd recommend working with our support team through an Azure Support Request or the Microsoft 365 Online support process.
If you didn't save your backup codes, and you've lost the phone that you use for 2FA – try calling your phone network to transfer your old number over to a new phone. You'll need a new SIM card for that, and it could take a day or two for it to activate.
