Manage aliases on your Microsoft account

You can change the way you sign in and show up by adding aliases to your Microsoft account. An alias is an additional account name that can be an email address, phone number, or Skype name. It uses the same inbox, contact list, and account settings as the primary alias. You can sign in to your account with any alias—they all use the same password.

Some reasons to use aliases on your account include:

  • You're ready for a new email address, but don't want to lose all your settings and data.  
  • You want the flexibility of having several aliases that share the same subscriptions and inbox.


By default, the email address or phone number that you use to sign up for your Microsoft account is considered the primary alias. Your primary alias shows up as the main account name when you view your profile information. This can be changed at any time.

Any other aliases are considered secondary aliases. You can control which secondary aliases can be used to sign in to your Microsoft account.
