Accounts Enable or Disable Aliases to Sign in to Microsoft Account

This tutorial will show you how to allow or prevent aliases to be used to sign in to your Microsoft account.

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. This password is your Microsoft account password.

Your account's primary alias is the email address shown when you sign in on your Microsoft devices (such as a Windows PC, Xbox, or Windows Phone), and you can choose a different alias to be the primary one at any time.

You can choose which added aliases are allowed to sign in to your Microsoft account without having to remove aliases.
