To save, manage, and share ArcGIS web maps, you need an ArcGIS account. In this tutorial, you'll create a personal account, which gives you access to the free parts of the ArcGIS system. (There are also subscription-based organizational accounts.)
If you already have an Esri Global Account that you use to log in to Esri websites, such as the Resource Center and Support Site, you can register this account to serve as your ArcGIS personal account. Skip ahead to the section of this tutorial called Register your Esri Global Account.
Your user name appears in search results and descriptions of your maps. It can't be changed later, so choose it carefully. If your account represents a group, such as the East Valley GIS Society, you may want the user name to reflect this.
Your personal account also has a profile that can be made public (see the section Edit your profile). The profile heading concatenates the First Name and Last Name fields of your account. If your account represents a group, put part of the group's name in each field.
Your account is created and registered, and you're signed in to ArcGIS Online.
If you already have an Esri Global Account, you can register it with ArcGIS Online. Be sure this account suits your needs. For example, if the account is in your name but you plan to use it to make maps on behalf of a group, you should probably create a new personal account for the group.
Your account is now registered and you are signed in to ArcGIS Online.
Whether your account represents a group you belong to or you as an individual, your profile lends credibility to your maps.
Your completed profile is shown.
When you're signed in, your account name appears at the top of the ArcGIS Online home page. You can click it to edit your profile.
This is the second in a series of online mapping tutorials.
