Question

Need to Disable Authentication App and Access which is in my lost mobile

Answer 1

To disable access for a lost mobile device that uses an authentication app, you will need to disable the associated user account in Microsoft Entra ID. This will revoke access for any device that uses the device code associated with that user account. Here are the steps to do this:

1. Sign in to the Azure portal.
2. On the left navigation pane, select Microsoft Entra ID, and ensure that you're in the correct directory.
3. In the Manage list, select Users.
4. Find the user account associated with the lost device and select the name to open the user's profile.
5. On the toolbar, select Revoke sessions to revoke the user account's sessions.

Additionally, you may want to change the user account's password or completely disable the user account to enhance security.
