Manage your Microsoft account

You can change the way you sign in and show up to recipients by adding aliases to your Microsoft account. An alias is like a nickname for your account 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 into your account with an alias, and you only have to remember a single password for all of them.

Some reasons to use aliases on your account include:

• You’ve changed names, set up a personal business, or just want to try something new.
• 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.
• You want an alias that can’t be used to sign into your account so that you can give it out to companies or other people and know they can’t use it to access your info.

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 into your Microsoft account.

You can have up to ten aliases on your Microsoft account at any given time.
