Your sign-in experience is changing
The web browser sign-in experience is changing when you sign in to any product or service using your Microsoft account. Starting in February 2025, you will stay signed in automatically unless you sign out or use private browsing.If you sign in on your own computer, your browser will remember your sign-in information, but if you sign in on a computer, phone or tablet that doesn't belong to you, or is accessed by other people, you should follow the steps below to use a private browsing window instead.
Private browsing ensures that others won't be able to:
- Access your Microsoft account, OneDrive or Outlook.com mailbox.
- See your search and browsing history.
