Using classic Outlook for Windows in business environments
Hi, my name is Kelly, and I'm an independent consultant and I'm here to help.
If you lost your device with the Microsoft Authenticator app installed and need to reset it, follow the steps below:
Go to your Microsoft account login page and select "No longer have access to your phone?" or "No longer have access to the device?".
On the next screen, select "Yes" to the question "Did you lose your phone?". Then select "Yes" again to confirm that you want to reset the authenticator app.
Follow the steps to confirm your identity, which may include verifying your alternate email account or providing personal information.
After verification, you will receive a temporary security code via email or SMS that you can use to access your Microsoft account.
You can now install the Microsoft Authenticator app on a new device and set it up with your Microsoft account.
Note: If you still have access to the device with the Microsoft Authenticator app installed, it's important to unlink it from your account before resetting the authenticator app. To do so, open the Microsoft Authenticator app, select the account and tap "Delete Account" to remove it from your device. This will prevent issues when resetting the authenticator app.
