Change your Microsoft account password
The steps below describe how to change a known password. If you want to reset your password because you forgot it, see Step 1: Reset your Microsoft account password instead.
Change your password
Go to account.microsoft.com and if you’re not already signed in, sign in with the username and current password for the account you want to update.
From the navigation header, select Security and because you’re accessing sensitive info, you’ll need to enter the password for this account again.
From the Password security tile, select Change my password.
On the Change your password page, enter your current password and then enter your new password.
For additional security, select the optional checkbox which prompts you to update your password every 72 days.
