What is Meaning of "arcgis" and "enterprise" Login Type in User Report

[McKinneyPatrickPAContractor]

I have been reviewing my ArcGIS Online user report.  There is a column named "Login Type."  There are entries for both "arcgis" and "enterprise."

I wanted to know what these values mean?

There are a few users who have a value of "arcgis" that I believe are signing in with their organizational usernames.  I would expect them to be "enterprise."  But, I don't know what these values actually mean.

Thanks for any input.

Hi @McKinneyPatrickPAContractor,

arcgis are 'built-in' accounts.  Meaning, these accounts are stored within ArcGIS Online.

enterprise are organization-specific identity store accounts.  For example, you can configure SAML logins with ArcGIS Online
