There could be a couple of reasons why there is trouble accessing projects or logging into ArcGIS Online. If you are trying to login to ArcGIS Online or ArcGIS Pro and receive one of the following errors:
- "Unable to sign in. Logins are by invitation only. Please contact the administrator of the organization."
- "We were unable to sign you in using those credentials. Please contact your ArcGIS administrator for assistance."
This message is caused by:
- If you haven't used ArcGIS before - you may not have an account activated or need to complete the account activation process.
- You may need an account activated - request an ArcGIS Account.
- If you are using ArcGIS as part of a class, make sure to check for an email notification from "ArcGIS Online". Click the link in the email notification to complete your account activation.
- If you have used ArcGIS previously - log out and log back in using these instructions. Make sure that you log in using Google Chrome.
If this does not resolve the access issue, contact the IT Helpdesk and we can check to see if you have an account.
Browsers
Most Internet browsers (Safari, Chrome, Firefox, Edge) are compatible with ArcGIS Online - it is recommended to use Google Chrome. In some cases, Safari causes issues with the login or when trying to access shared projects.
