Email addresses and phone numbers associated with your Microsoft account are called aliases and they use the same contacts, online storage, subscriptions, and account settings. 

You can use any of your aliases to sign in to Microsoft services or your Windows and Xbox devices, and you can select any of them for sending and receiving email. Your aliases share a single password.

You can also add a different email address (such as your partner's email) as a way to verify sign in information.
