If you are not able to sign in successfully to ArcGIS Pro, you may see one of the error messages below.
Your account does not have a license assigned
The message Your account does not have an ArcGIS Pro Named User license assigned means that your ArcGIS organization administrator has not assigned you an ArcGIS Pro license (or may have revoked your license).
Contact your ArcGIS organization administrator and ask to be assigned an ArcGIS Pro license. If you don't know who your ArcGIS organization administrator is, see Find your organization administrator below.
If you are the organization administrator, see Assign Named User licenses in ArcGIS Online for more information.
Your account has a Level 1 membership
The message Your account has a Level 1 membership and is not authorized for ArcGIS Pro means that you are a Level 1 member of your ArcGIS organization. ArcGIS organizations have both Level 1 and Level 2 members. Only Level 2 members can be assigned ArcGIS Pro licenses.
Contact your ArcGIS organization administrator and ask to be assigned an ArcGIS Pro license. The administrator will first need to change your membership level from Level 1 to Level 2. If you don't know who your ArcGIS organization administrator is, see Find your organization administrator below.
Your account is an ArcGIS public account
The message Your account could not be used to authorize ArcGIS Pro because it is an ArcGIS Public Account means that your account is not part of an ArcGIS organization. An ArcGIS public account has limited access to ArcGIS Online and does not allow you to use ArcGIS Pro.
You can confirm that your account is a public account by signing in to ArcGIS Online from a web browser. If the URL is www.arcgis.com/home/index.html, your account is public. An ArcGIS organization account has the form www.<orgname>.maps.arcgis.com/home/index.html.
If you don't have an ArcGIS organization account, you can sign up for an ArcGIS free trial that includes an ArcGIS Online organization and access to ArcGIS Pro, ArcGIS Pro extension products, and other apps.
Find your organization administrator
Sign in to your ArcGIS organization account from a web browser. On the Home tab, look for the Contact Us link at the bottom of the page.
Click the Contact Us link to send an email to your organization administrator or contact person.
Alternatively, after signing in to your ArcGIS organization account, click Organization at the top of the site. On the Overview tab, your administrative contact (or contacts) are displayed in the upper right corner of the page. Click the administrator's name to access their profile.
If you aren't able to determine who your administrator is, contact Esri for assistance.
