1. Visit the MSN Account Services website, and then click Sign in. If you're already signed in with your Windows Live ID, you won't be prompted to sign in again.
2. Type the user name and password that you're using to sign in to Messenger, and then click OK.

If you're successfully signed in, you'll see a Sign out button. If you see an error message, your password may be incorrect, or your account may have expired.

Click Forgot your password? at the bottom of the Messenger sign-in window, and then follow the on-screen instructions.

If Messenger is trying to connect automatically without prompting you to enter your password, you may have saved the incorrect password.

2. Type your password in the Password box, and then select the Remember my password check box to store the updated password.
3. Select the Sign me in automatically check box to turn on automatic sign-in.
