How to Change Sign-in Preferences of your Microsoft Account Aliases

information   Information
An account alias is an email address or phone number that you use to sign in to your Microsoft account. You can have multiple aliases, and use any of them with Microsoft services such as, Skype, OneDrive, Office, Xbox, Windows and more.

Your primary alias appears on devices such as your Xbox, Surface, and Windows Phone, and is the email OneDrive sends from when you share. You can choose a different alias to be the primary one at any time.

You can choose which added aliases are allowed to be used to sign-in to your Microsoft account.

This tutorial will show you how to change your sign-in preferences for which aliases are allowed to sign-in to your Microsoft account.

Here's How:

1. Sign in to the Microsoft account website.

2. Click/tap on the Change sign-in preferences link under the Sign-in preferences section at the bottom. (see screenshot below)

To increase security, only allow sign-in from email mailboxes, phone numbers, and Skype names you monitor.
