Sign in to Outlook.com
In a private browser window, go to Outlook.com.
Sign in with your email address and password. If you need help, see How to sign in to or out of Outlook.com.
Note: If you've turned on two-factor authentication for your account, you can receive and use verification codes in the Authenticator app even if your phone isn't connected to the internet. Just open the app, copy the verification code, and enter it when prompted during the sign-in process.
Close the private browser window
Make sure to close the private browser window when you're done so other people who use the device can't access your Outlook.com account. When you close a private browser window, it deletes your personal information. Another person who goes to Outlook.com on that device won't see your email address or password on the sign-in page.
