I've been accessing our ArcGIS Online site via token in ArcGIS Python API without any issues for the past couple of months.
I seem to be having issues authenticating via an access token now.
from arcgis.gis import GIS
gis = GIS(url=portal, token=accessToken)
In the API references , I also realised that it mentions the below:
Optional string. This is the Enterprise token for built-in logins. This parameter is only honored if the username/password is None and the security for the site uses BUILT-IN security.
Our AGOL site is configured with Enterprise Login and I use the token authentication to login with my Enterprise login.
Did something change recently and is this still a supported method of authentication? It has significant ramifications to our org if it is no longer supported.
