Summary ​

This article walks you through changing your Microsoft 365 password from the web portal while you are already signed in. Use this when your password is expiring or you want to update it proactively.

Prerequisites ​

  • Sign in to your Microsoft 365 account before starting.
  • Make sure you know your current password.

Instructions ​

1. Change Your Password from the M365 Portal ​

The fastest route through the Microsoft 365 web interface.

  1. Open a browser and go to https://myaccount.microsoft.com.
  2. If prompted, sign in with your work email and current password.
  3. On the My Account page, click Password in the left sidebar (or click the Change password link on the overview tile).
  4. Enter your Old password.
  5. Enter your New password and then Confirm new password.
  6. Click Submit.
  7. A confirmation message will appear: "Your password has been changed."

2. Change Your Password from Any M365 App ​

You can also reach the password page directly from Outlook, Teams, or any Microsoft 365 app on the web.

  1. Click your profile picture (or initials) in the top-right corner of any M365 app.
  2. Click View account (or My account).
  3. This opens the same My Account portal.
  4. Click Password in the left sidebar and follow steps 4–7 from Method 1 above.

3. Update Saved Passwords on Your Devices ​

After changing your M365 password, some apps and devices may still have the old password cached.

  1. Outlook Desktop — Outlook will prompt you for the new password the next time it connects. Enter it when prompted.
  2. Mobile Devices — Open the Outlook app (or Teams) on your phone. When prompted, sign in with the new password.
  3. Browser Saved Passwords — If your browser offers to update the saved password, click Update to avoid future sign-in issues.
