Revoke Easy Access to Outlook.com on Trusted Devices

It's easy to log into Outlook.com and designate "trusted devices," even when you have two-step verification in place. When you lose trust in a device or lose the device itself, you should revoke access to the device. Authentication using both password and code is required in all browsers, but not in applications that use specific passwords to log into your Outlook.com account via POP.

5. Enter the email address of your Microsoft account, then select Next.

6. Enter your password, then select Sign in.

8. Select Next to setup Windows Hello.

9. You may be prompted to enter a PIN if you previously set up one.

10. Select Verify to verify your identity on the PC.

11. Choose how you want to receive a security code (through text, email, or phone), then select Next.

12. Enter the code you received, then select Next.

13. To verify your system has been added, select Manage my Microsoft account.

14. In the Microsoft account page, select Sign in.

15. Enter your login account, then select Next.

16. Enter your password, then select Sign in.

    Select Keep me signed in to avoid logging in frequently.

17. Under Devices, select All Devices. Or select your newly added device if it displays in the list of devices.

18. You can view your newly added device, see details, and manage the device.
