How do I change my MSN Messenger or Hotmail password?
Messenger and Hotmail use the .NET Passport service for authentication, so this means you’ll need to change your password there. Rather than trying to remember the steps or the pages to go to, I do this:
Become a Patron of Ask Leo! and go ad-free!
Fire up MSN Messenger
File, Sign Out, if signed in
File, Sign In… (not the entry
that may already have your account name listed).
At the bottom of the resulting dialog box, click on Help
And on the resulting web page, click on Change My Password.
You’ll then be prompted to log in to .NET Passport (using your old password)
and then given the opportunity to change your password.
Remember that this applies to all services which use .NET Passport to login in, including Hotmail, MSN Messenger and more.
