I can't remember the Microsoft account or password I use with Office

If your copy of Office is one of those listed under the Office for home plans you need a Microsoft account to install Office from My Office Account. If you can't remember the Microsoft account username that you used to set up Office, you won't be able to install or reinstall Office, or manage your Office 365 subscription.

If you can't remember your password and you'd like to reset it, see the section below, Reset the password for your Microsoft account.

If you don't have a current installation of Office 2016; or you haven't yet redeemed a product key for Office 2016 or Office 2013, you'll need to contact support.

The following are a couple of options to help you remember your Microsoft username.
