Where you can’t use security codes, use app passwords

Some apps (like the mail apps on some phones) or devices (like the Xbox 360) can’t use regular security codes. If you see an “incorrect password” error on an app or device after you turn on two-step verification, but you’re sure your password was correct, that means you’ll need an app password for that app or device.

App passwords are only available if you use two-step verification. If you don’t have two-step verification turned on, you won’t see the App passwords section on the Additional security options page.

How to create a new app password

To create a new app password for an app or device, take the following steps. You can repeat these steps to create an app password for as many apps or devices as you need.

1. Go to the Security basics page and sign in to your Microsoft account.
2. Select More security options.
3. Under App passwords, select Create a new app password. A new app password is generated and appears on your screen.
4. Enter this app password where you would enter your normal Microsoft account password in the application.
